At this time, the charger120 may be provided in such a way that at least a part of the body 11,in which the battery 16 is arranged, is seated thereon so as to chargethe battery 16.

As described above, the conventional docking station may be configuredto supply power to the battery when the cleaner is docked to the dockingstation. The docking station 100 according to an embodiment of thedisclosure may additionally increase the convenience of the consumer byautomatically discharging dust collected inside the dust collectingchamber 20 upon docking of the cleaner 10 to the docking station 100.

However, the docking station 100 according to an embodiment of thedisclosure may perform only a function of automatically discharging dustcollected in the dust collecting chamber 20 without charging the cleaner10.

In the conventional manner, a user has to directly remove foreignsubstances collected in the dust collecting chamber 20 after the use ofthe cleaner 10. However, the docking station 100 according to anembodiment of the disclosure may automatically remove dust collected inthe dust collecting chamber 20 by being directly docked to the dustcollecting chamber 20 upon docking of the cleaner 10.

By including a suction device 130, the docking station 100 may dischargedust collected in the dust collecting chamber 20 from the dustcollecting chamber 20.

The suction device 130 may include an intake flow path 132.

The intake flow path 132 may transfer the air flow generated by thesuction fan 131 to the dust collecting chamber 20. That is, the intakeair flow generated by the suction fan 131 may be transferred into thedust collecting chamber 20 along the intake flow path 132, and theforeign substance inside the dust collecting chamber 20 may bedischarged to the outside of the dust collecting chamber 20 according tothe intake air flow.

One end of the intake flow path 132 may be connected to the dustcollecting chamber 20, and the other end of the intake flow path 132 maybe connected to a collector (not shown) configured to collect thesuctioned foreign substance.

The collector (not shown) may have an inner space larger than that ofthe dust collecting chamber 20.

Although not shown in the drawing, the collector (not shown) may beprovided in the shape of a collection bag configured to transmit air toallow the intake air flow generated by the suction fan 131 to flow intothe intake flow path 132 and configured to prevent dust from beingtransmitted.

However, the shape of the collector (not shown) is not limited thereto,and thus the collector (not shown) may be provided in the shape of anadditional dust collecting chamber communicating with the intake flowpath 132 and the suction fan 131. The additional dust collecting chambermay be formed in a multi-cyclone type in the same manner as the dustcollecting chamber 20, so as to collect foreign substances introducedfrom the dust collecting chamber 20.

The collector (not shown) may be arranged in a first inner space 111formed by the body housing 110. The first inner space 111 may beprovided to be opened and closed by a first cover 112 arranged in frontof the body housing 110.

When the collector (not shown) is fully filled with the foreignsubstances, a user may open the first cover 112 and separate thecollector (not shown) from the body housing 110 so as to remove theforeign substance collected in the collector (not shown).

The suction fan 131 may be arranged in a second inner space 113 formedby the housing. The second inner space 113 may be provided to be openedand closed by a second cover 114 arranged in front of the body housing110.

The second cover 114 may be configured to discharge air suctioned by thesuction fan 131. An inner side surface of the second cover 114 may beequipped with an additional filter (not shown) configured toadditionally filter out foreign substances in the discharged air.

The first inner space 111 and the second inner space 113 may be providedto communicate with each other. Thus, in response to driving the suctionfan 131, the intake air flow may be transferred to the intake flow path132 through the first inner space 111 and the second inner space 113,and the intake air flow may be transferred to the dust collectingchamber 20 through the intake flow path 132.

However, the structure of the first inner space 111 and the second innerspace 113 is not limited thereto, and thus the first inner space 111 andthe second inner space 113 may be formed as one space without beingdivided in the body housing 110.

The charger 120 described above may be arranged at the most upper end ofthe body housing 110.

The body housing 110 may include a docking housing 140, and the dockinghousing 140 allows the dust collecting chamber 20 and the dustcollecting guide 30 to be docked to the inside of the housing upon thedocking of the handle 14 to the charger 120.

Accordingly, in response to the closed state of the first door 22 andthe second door 23, the foreign substances may be prevented from leakingbetween the first door 22 and the second door 23.

The first door 22 may include a first pressed portion 22 b arranged on aside opposite to the first contact portion 22 c and configured to rotatethe first door 22 about the first rotary shaft 22 a by being pressed bya first opening rib 132 a described later. The first door 22 may beprovided such that the first contact portion 22 c, the first rotaryshaft 22 a, and the first pressed portion 22 b are sequentially arrangedoutward from the center of the lower end of the dust collecting chamber20.

The second door 23 may include a second pressed portion 23 b arranged ona side opposite to the second contact portion 23 c and configured torotate the second door 23 about the second rotary shaft 23 a by beingpressed by a second opening rib 132 b described later. The second door23 may be provided such that the second contact portion 23 c, the secondrotary shaft 23 a, and the second pressed portion 23 b are sequentiallyarranged outward from the center of the lower end of the dust collectingchamber 20.

The first door 22 and the second door 23 may be provided with a doorside elastic member (not shown) configured to elastically support thefirst door 22 and the second door 23 so as to be elastically coupled tothe dust collecting chamber 20.

The door side elastic member (not shown) may limit the rotation of thefirst door 22 and the second door 23 so as to maintain the first door 22and the second door 23 in the closed state.

In response to the downward rotation of the first door 22 and the seconddoor 23 by an external pressure, the door side elastic member (notshown) may elastically support the first door 22 and the second door 23upward. Accordingly, in response to releasing the external pressure, thefirst door 22 and the second door 23 rotated downward may be rotatedupward again and arranged in the closed state.

The intake flow path 132 may include the first opening rib 132 a and thesecond opening rib 132 b, which are arranged inside the intake flow path132 and configured to push the first pressed portion 22 b and the secondpressed portion 23 b upward upon the docking of the dust collectingchamber 20 to the intake flow path 132.

The dust collecting chamber 20 may be provided to be inserted into oneend of the intake flow path 132 by passing through the first opening141. The dust collecting chamber 20 is inserted into the intake flowpath 132 in the vertical direction, and particularly, while the dustcollecting chamber 20 is inserted into the intake flow path 132 in thevertical direction, the first pressed portion 22 b and the secondpressed portion 23 b may be pressed upward by the first opening rib 132a and the second opening rib 132 b arranged inside the intake flow path132.

As for the first door 22, the first contact portion 22 c may be rotateddownward about the first rotary shaft 22 a while the first pressedportion 22 b is pressed upward.

As for the second door 23, the second contact portion 23 c may berotated downward about the second rotary shaft 23 a while the secondpressed portion 23 b is pressed upward.

The first opening rib 132 a and the second opening rib 132 b each may beprovided to protrude toward the center of the intake flow path 132 fromthe inner circumferential surface of the intake flow path 132.

The first opening rib 132 a and the second opening rib 132 b may bearranged on opposite sides with respect to the center of the intake flowpath 132.

As mentioned above, the first door 22 and second door 23 may beelastically supported upward by the door side elastic member (not shown)upon opening the first door 22 and the second door 23 downward.

Upon docking the dust collecting chamber 20 to the intake flow path 132in the downward direction, the first opening rib 132 a and the secondopening rib 132 b may press the first pressed portion 22 b and thesecond pressed portion 23 b, respectively, and then support the firstpressed portion 22 b and the second pressed portion 23 b while the dustcollecting chamber 20 is docked to the intake flow path 132.

Accordingly, the first door 22 and the second door 23 may be maintainedin an open state while the dust collecting chamber 20 is docked to theintake flow path 132.

Upon separating the dust collecting chamber 20 from the intake flow path132, the first pressed portion 22 b and the second pressed portion 23 bmay be moved upward and separated from the first opening rib 132 a andthe second opening rib 132 b.

Therefore, the first opening rib 132 a and the second opening rib 132 bmay not press the first pressed portion 22 b and the second pressedportion 23 b and thus the first door 22 and the second door 23 may berotated upwards by being elastically supported by the door side elasticmember (not shown).

Accordingly, the first door 22 and the second door 23 are opened by thefirst opening rib 132 a and the second opening rib 132 b upon dockingthe dust collecting chamber 20 to the intake flow path 132. Uponseparating the dust collecting chamber 20 from the intake flow path 132,the first door 22 and the second door 23 may close the dust collectingchamber 20 again by the door side elastic member (not shown).

The first opening rib 132 a and the second opening rib 132 b may beprovided to have different heights in the vertical direction. Withrespect to the vertical direction, an upper end of the first opening rib132 a may be provided to extend to a position higher than an upper endof the second opening rib 132 b.

Upon docking the dust collecting chamber 20 to the intake flow path 132in a state in which the upper end of the first opening rib 132 a extendshigher than the upper end of the second opening rib 132 b, the firstpressed portion 22 b may be pressed before the second pressed portion 23b and thus the first door 22 may be first opened.

Sequentially, the second pressed portion 23 b may be pressed by theupper end of the second opening rib 132 b and then the second door 23may be opened after the first door 22 is opened.

That is, the first door 22 and the second door 23 may be sequentiallyopened because the heights of the upper ends of the first opening rib132 a and the upper ends of the second opening rib 132 b are differentfrom each other. On the contrary, upon separating the dust collectingchamber 20 from the intake flow path 132, the second pressed portion 23b may move upward, and the contact with the second opening rib 132 b maybe terminated before the contact between the first pressed portion 22 band the first opening rib 132 a is terminated. Therefore, the seconddoor 23 may be closed before the first door 22.

By opening and closing the first door 22 and the second door 23sequentially, it is possible to prevent the first door 22 and the seconddoor 23 from being opened at the same time. Accordingly, it is possibleto prevent the dust collected in the dust collecting chamber 20 fromscattering instantaneously. In addition, it is possible to prevent acase in which while the first door 22 and the second door 23 arerotated, the first contact portion 22 c and the second contact portion23 c do not reach the closed position and thus before the first door 22and the second door 23 are rotated to the closed position, the endportion of the first contact portion 22 c and the end portion of thesecond contact portion 23 c are in contact with each other and jammedwith each other.

In addition, as described above, because the second contact protrusion23 d and the first contact protrusion 22 d sequentially overlap eachother in the vertical direction, the first door 22 may be opened beforethe second door 23 is opened, and the second door 23 may be closedbefore the first door 22 is closed.

Because the second contact protrusion 23 d is arranged above the firstcontact protrusion 22 d, upon opening the second door 23 before thefirst door 22, the second contact protrusion 23 d may be rotateddownward and at this time, the first contact protrusion 22 d may limitthe rotation of the second contact protrusion 23 d.

As described above, the second contact protrusion 23 d and the firstcontact protrusion 22 d may prevent the foreign substance from escapingfrom the dust collecting chamber 20 through between the first door 22and the second door 23 while the second contact protrusion 23 d and thefirst contact protrusion 22 d allows the first door 22 and the seconddoor 23 to be sequentially opened or closed.

In this way, due to the arrangement of the first opening rib 132 a andthe second opening rib 132 b and the arrangement of the second contactprotrusion 23 d and the first contact protrusion 22 d, the first door 22may be opened before the second door 23 and the second door 23 may beclosed before the first door 22.

Hereinafter a configuration of a dust collecting chamber door 21according to a second embodiment of the disclosure will be described. Aconfiguration other than the dust collecting chamber door 21 describedbelow is the same as that of the cleaning apparatus 1 according to thefirst embodiment of the disclosure, and thus a description thereof willbe omitted.

FIG. 8 is a sectional perspective view of a part of a dust collectingchamber of a cleaner according to a second embodiment of the disclosure.

Referring to FIG. 8, a first door 22 and a second door 23 of a dustcollecting chamber door 21 according to another embodiment of thedisclosure may include a magnet 25, respectively.

According to the first embodiment of the disclosure described above, thefirst door 22 and the second door 23 include the first contactprotrusion 22 d and the second contact protrusion 23 d, respectively.However, the first door 22 and the second door 23 according to thesecond embodiment of the disclosure do not include contact protrusions.

Therefore, the first contact portion 22 c and the second contact portion23 c may be provided in a planar shape.

The first door 22 includes a first magnet 25 a arranged adjacent to thefirst contact portion 22 c and arranged inside the first door 22.

The second door 23 includes a second magnet 25 b arranged adjacent tothe second contact portion 23 c and arranged inside the second door 23.

In response to the closed state of the first door 22 and the second door23 by the first magnet 25 a and the second magnet 25 b, it is possibleto tightly maintain the first contact portion 22 c and the secondcontact portion 23 c at the contact state.

Accordingly, the foreign substance inside the dust collecting chamber 20may be prevented from leaking out through between the first door 22 andthe second door 23.

Hereinafter the flow rate regulator 150 will be described.

FIG. 9 is a cross-sectional view taken along line BB′ of FIG. 3 when aflow path cover is closed in a state in which the cleaner is coupled tothe station according to the first embodiment of the disclosure and FIG.10 is a cross-sectional view taken along line BB′ of FIG. 3 when theflow path cover is opened in a state in which the cleaner is coupled tothe station according to the first embodiment of the disclosure.

As described above, the foreign substance collected in the dustcollecting chamber 20 may be discharged to the outside through thesuction device 130 and collected by a collector (not shown) of thesuction device 130.

Air and foreign substances in the dust collecting chamber 20 may bedischarged to the outside through the dust collecting chamber door 21 ofthe dust collecting chamber 20 and the intake flow path 132, but some ofthe foreign substances may be not discharged to the outside by beingcaught by the inner structure of the dust collecting chamber 20.

For example, because foreign substances such as hair are caught by theinternal structure of the dust collecting chamber 20 and are notdischarged to the outside, the foreign substance may be left in the dustcollecting chamber 20 due to the intake air flow that is generated tothe lower side of the dust collecting chamber door 21.

The intake air flow delivered to the dust collecting chamber 20 may beformed to be directed to only the downward direction of the dustcollecting chamber 20. Accordingly, some foreign substance may have aresistance to the direction in which the intake air flow is formed, andthus the foreign substances may be not discharged to the outside of thedust collecting chamber 20 due to the intake air flow.

Accordingly, a difficulty may occur in that the foreign substance insidethe dust collecting chamber 20 is not effectively removed.

In order to ease the difficulty, the docking station 100 according to anembodiment of the disclosure may include the flow rate regulator 150configured to selectively provide additional outside air to the dustcollecting chamber 20 in addition to the intake air flow.

While the intake air flow is supplied to the dust collecting chamber 20and the internal air of the dust collecting chamber 20 is suctioned bythe suction device 130, the flow rate regulator 150 may variously changethe internal air flow of the dust collecting chamber 20 by changing theflow rate of the inside of the dust collecting chamber 20.

As described above, in the dust collecting chamber 20, the air flow isdirected to the lower side by the suction fan 131. Particularly, becausethe internal air of the dust collecting chamber 20 is continuouslydischarged to the outside by the suction fan 131, the negative pressuremay be generated in the dust collecting chamber 20, in comparison withthe atmospheric pressure.

At this time, upon additionally supplying the outside air to the dustcollecting chamber 20 by the flow rate regulator 150, the air pressureinside the dust collecting chamber 20 may be instantly raised. As theair pressure is raised, the flow of air inside the dust collectingchamber 20 may be changed, and the flow of air that has been directed toonly downward may be changed in all directions.

As the flow rate inside the dust collecting chamber 20 is changed, airmay be spread in all directions in the internal space of the dustcollecting chamber 20, and thus the air flow, which has been directed toonly the lower side, may be changed in various directions.

As the direction of the air flow is changed instantaneously, someforeign substance having a resistance to the downward direction may loseresistance by the air flowing in the other direction and some foreignsubstance may be separated out of the dust collecting chamber 20together with the air flow.

The flow rate regulator 150 is configured to provide air to the dustcollecting chamber 20 for a predetermined period of time and stopsupplying air for a predetermined period of time. The flow rateregulator 150 may periodically change the air flow inside the dustcollecting chamber 20 by repeatedly supplying the outside air to thedust collecting chamber 20 or stopping supplying air.

Referring to FIGS. 9 and 10, the flow rate regulator 150 may include aconnecting flow path 151 connected to the dust collecting guide 30.

One end of the connecting flow path 151 may be connected to the dustcollecting guide 30, and the other end of the connecting flow path 151may be provided to allow outside air to flow therein.

The connecting flow path 151 may be arranged in the docking housing 140and connected to the second opening 142. One end of the connecting flowpath 151 may communicate with the second opening 142, and the other endof the connecting flow path 151 may be arranged in the docking housing140 to allow air of the docking housing 140 to flow therein.

Because the dust collecting guide 30 is provided to communicate with thedust collecting chamber 20 as described above, the outside air may flowinto the dust collecting chamber 20 through the dust collecting guide 30upon opening the dust collecting guide 30 toward the outside (refer toFIG. 4).

The flow rate regulator 150 includes a flow path cover 152 configured tocover the other end of the connecting flow path 151.

The flow path cover 152 may include a hinge 152 a arranged on one sideof the flow path cover 152 and configured to allow the flow path cover152 to be rotatably coupled to the connecting flow path 151.

The flow path cover 152 may be rotatable with respect to the connectingflow path 151 using the hinge 152 a as a rotation axis. In order toclose the connecting flow path 151, the flow path cover 152 may berotated downward about the hinge 152 a at a position covering the otherend of the connecting flow path 151.

The flow rate regulator 150 may include a cover elastic member 156configured to elastically support the flow path cover 152.

The cover elastic member 156 may be configured to allow the flow pathcover 152 to be elastically supported upward.

The flow path cover 152 may be pressed upward by the cover elasticmember 156. Accordingly, the cover elastic member 156 may elasticallysupport the flow path cover 152 to allow the flow path cover 152 to berotated to the other end direction of the connecting flow path 151 withrespect to the hinge 152 a.

Therefore, in response to no external pressure, the flow path cover 152may close the connecting flow path 151 by the cover elastic member 156.However, when the flow path cover 152 is pressed downward by an externalpressure, the flow path cover 152 may be rotated downward about thehinge 152 a, thereby being opened to the outside of the connecting flowpath 151.

The flow rate regulator 150 may include an opening and closing unit 155configured to selectively open and close the connecting flow path 151through the flow path cover 152.

When the opening and closing unit 155 separates the flow path cover 152from the connecting flow path 151 and the other end of the connectingflow path 151 is opened to the outside, the outside air may beintroduced into the connecting flow path 151 and the introduced outsideair may flow into the inside of the dust collecting chamber 20 throughthe connecting flow path 151 and the dust collecting guide 30.

The opening and closing unit 155 may include a drive motor 153configured to generate a rotational force and an opening and closingmember 154 configured to be rotatable by being connected to the drivemotor 153 so as to press the flow path cover 152 toward one directionthrough the rotation thereof.

The flow path cover 152 may include a pressed portion 152 b arranged onone side of the flow path cover 152 and pressed by the opening andclosing member 154.

The pressed portion 152 b may be arranged on the opposite side of thehinge 152 a. Accordingly, when the pressed portion 152 b is pressed bythe opening and closing member 154, the pressed portion 152 b may berotated about the hinge 152 a toward the direction in which the pressedportion 152 b is pressed by the opening and closing member 154.

The opening and closing member 154 may press the pressed portion 152 bdownward. Accordingly, the flow path cover 152 may be pressed downwardwith respect to the hinge 152 a and then the flow path cover 152 may bearranged in an open position.

Therefore, when the opening and closing member 154 presses the pressedportion 152 b, the flow path cover 152 may be opened and the connectingflow path 151 may be opened to the outside.

When the pressing of the opening and closing member 154 is terminated,the pressed portion 152 b may be rotated upward by the cover elasticmember 156, thereby closing the flow path cover 152.

Particularly, a rotation axis A of the shaft of the drive motor 153 anda rotation axis B of the hinge 152 a may extend in parallel to eachother. The opening and closing member 154 and the flow path cover 152connected to the drive motor 153 may include the rotation shafts A and Bhaving the same direction.

It is appropriate that the rotation axis A of the shaft of the drivemotor 153 and the rotation axis B of the hinge 152 a may be arranged atthe same height in the vertical direction.

When the opening and closing member 154 is rotated in one direction inassociation with the driving of the drive motor 153, the pressed portion152 b may be pressed downward by the opening and closing member 154 andthus the flow path cover 152 may be rotated to a direction opposite tothe opening and closing member 154.

The opening and closing member 154 may include a pressing protrusion 154a protruding in a radial direction of the rotation axis of the openingand closing member 154 and provided to press the pressed portion 152 b.The pressing protrusion 154 a may be provided in plural and theplurality of the pressing protrusions 154 a may be radially arrangedabout the rotation axis of the opening and closing member 154. It isappropriate that four pressing protrusions 154 a may be formed.

A non-pressing portion 154 b configured to not press the pressed portion152 b upon the rotation of the opening and closing member 154 may beprovided among the plurality of pressing protrusions 154 a.

Referring to FIG. 9, when any one of the plurality of pressingprotrusions 154 a presses the pressed portion 152 b while the openingand closing member 154 rotates, the flow path cover 152 may be rotatedto a direction, which is opposite to the rotation direction of theopening and closing member 154, by the opening and closing member 154,and then opened.

That is, it is assumed that an imaginary line between the rotation axisA of the shaft of the drive motor 153 and the rotation axis B of thehinge 152 a is a line L, and when any one of the plurality of pressingprotrusions 154 a passes through the line L, any one of the plurality ofpressing protrusions 154 a may press the pressed portion 152 b, therebyopening the flow path cover 152.

As the opening and closing member 154 continues to rotate, any one ofthe plurality of pressing protrusions 154 a may continue to rotatedownward and rotate in a direction away from the pressed portion 152 bdue to the radial distance of the opening and closing member 154.

That is, due to the continuous rotation of the opening and closingmember 154, any one of the plurality of pressing protrusions 154 a maypass through the line L, and thus the pressing of any one of theplurality of pressing protrusions 154 a against the pressing portion 152b may be terminated.

The flow path cover 152 may be rotated in the same rotational directionas the opening and closing member 154 so as to close the connecting flowpath 151 again.

Referring to FIG. 10, the opening and closing member 154 may continue torotate while the flow path cover 152 closes the connecting flow path151. At this time, the non-pressing portion 154 b may pass through theline L.

The non-pressing portion 154 b is configured to not press the pressedportion 152 b upon the rotation of the opening and closing member 154,as mentioned above. As for the non-pressing portion 154 b, a length thatextends in the radial direction of the rotation axis A of the openingand closing member 154 may be relatively less than the pressingprotrusion 154 a.

As for the non-pressing portion 154 b, the length extending in theradial direction of the rotation axis A of the opening and closingmember 154 may be set to prevent the non-pressing portion 154 b frombeing in contact with the pressed portion 152 b when the non-pressingportion 154 b passes through the line L.

Accordingly, an external force is not applied to the pressed portion 152b while the non-pressing portion 154 b passes through the line L, andthus the flow path cover 152 may maintain the closed state of theconnecting flow path 151.

Sequentially, another one of the plurality of pressing protrusions 154 acontinues to rotate downward in accordance with the continuous rotationof the opening and closing member 154, and then the another one of theplurality of pressing protrusions 154 a passes through the line L.Therefore, the opening and closing member 154 may press the pressedportion 152 b again, thereby opening the flow path cover 152.

As described above, the opening and closing member 154 may alternatelyopen and close the flow path cover 152 as the plurality of pressingprotrusions 154 a and the non-pressing portion 154 b alternately passthrough the line L.

The connecting flow path 151 may be periodically opened to and closedfrom the outside, the outside air may flow into the dust collectingguide 30 for a predetermined period of time, flowing of the air to thedust collecting guide 30 may be blocked for a predetermined period oftime, and the air may flow into the dust collecting guide 30 for apredetermined period of time, again.

As such a mechanism is repeated, the flow rate of the outside air, whichis additionally introduced into the dust collecting chamber 20, may berepeatedly changed, and thus the flow of air inside the dust collectingchamber 20 may be variously changed.

The direction of air flow may vary according to the change in the flowrate of the internal air of the dust collecting chamber 20, and thus theforeign substances left in the dust collecting chamber 20 may bedischarged to the outside with the air flow that is generated in thevarious directions.

Hereinafter the driving sequence of the docking station 100 will bedescribed.

FIG. 11 is a flow chart illustrating driving of the station shown inFIG. 1 according to an embodiment of the disclosure.

Referring to FIG. 11, in response to docking the cleaner 10 to thedocking station 100 as mentioned above at operation S100, the switchunit 160 may detect the docking of the cleaner 10.

Accordingly, the switch unit 160 may transmit an electrical signal tothe controller (not shown) or may be directly connected to the suctiondevice 130 and the flow rate regulator 150 to transmit the electricalsignal at operation S200.

The first switch 161 may provide an electrical signal for driving thesuction fan 131, to the suction device 130. The first switch 161 mayprovide a signal to the suction device 130 to drive the suction fan 131for about one minute at operation S310.

The second switch 162 may provide an electric signal for driving thedrive motor 153 to the flow rate regulator 150. The second switch 162may provide a signal to the flow rate regulator 150 to drive the drivemotor 153 for about one minute at operation S320.

The first switch 161 and the second switch 162 may simultaneously drivethe suction device 130 and the flow rate regulator 150 for about oneminute.

In response to elapsed time that is less than one minute, the firstswitch 161 and the second switch 162 may continuously transmit a signalto drive the suction device 130 and the flow rate regulator 150.

However, the predetermine period of time is not limited thereto, and thefirst switch 161 and the second switch 162 may provide a signal to drivethe suction device 130 and the flow rate regulator 150 for one minute orless or for one minute or more. Alternatively, any one of the suctiondevice 130 and the flow rate regulator 150 may be first driven at apredetermined interval without being driven simultaneously.

In response to elapsed time that is one minute, the first switch 161 andsecond switch 162 may stop driving of the suction device 130 and theflow rate regulator 150, and transmit a signal to the suction device 130and the flow rate regulator 150 at operation S400.

As mentioned above, because the flow rate regulator 150 is driven whilethe suction device 130 is driven, the outside air may be additionallysupplied to the inside of the dust collecting chamber 20 while theintake air flow is generated inside of the dust collecting chamber 20.Therefore, it is possible to change the flow rate of the dust collectingchamber 20, thereby changing the air flow.

Hereinbefore a case in which the switch unit 160 directly transmits anelectrical signal to the suction device 130 and the flow rate regulator150 has been described. However, the disclosure is not limited thereto,and thus the switch unit 160 may transmit an electrical signal to thecontroller (not shown) and then the controller (not shown) may transmitthe electrical signal to the suction device 130 and the flow rateregulator 150.

Hereinafter an opening and closing member 154′ according to a thirdembodiment of the disclosure will be described. A configuration otherthan the opening and closing member 154′ according to the thirdembodiment of the disclosure is the same as the configuration accordingto the first embodiment of the disclosure, and thus a descriptionthereof will be omitted.

FIG. 12 is a cross-sectional view taken along line BB′ of FIG. 3 when aflow path cover is closed in a state in which a cleaner is coupled to astation according to a third embodiment of the disclosure.

Referring to FIG. 12, four pressing protrusions 154 a of the opening andclosing member 154 may be provided according to the first embodiment ofthe disclosure. However, the number of the pressing protrusion is notlimited thereto, and thus four or less or more of pressing protrusions154 a may be provided.

The opening and closing member 154′ according to the third embodiment ofthe disclosure may include two pressing protrusions 154 a′.

As the number of the pressing protrusions 154 a′ decreases, a rangeoccupied by a non-pressing portion 154 b′ may increase. Accordingly, atime for opening the flow path cover 152 upon driving the opening andclosing member 154′ according to the third embodiment of the disclosuremay become shorter than a time for opening the flow path cover 152 upondriving the opening and closing member 154 according to the firstembodiment of the disclosure.

In response of the one rotation of the opening and closing member 154′according to the third embodiment of the disclosure, the opening andclosing member 154′ may open the flow path cover 152 twice, but inresponse of the one rotation of the opening and closing member 154according to the first embodiment of the disclosure, the opening andclosing member 154 may open the flow path cover 152 four times.

Therefore, the flow rate regulator 150′ according to the thirdembodiment of the disclosure may provide a smaller amount of outside airto the dust collecting chamber 20 than that of the flow rate regulator150 according to the first embodiment of the disclosure.

On the contrary, although not shown in the drawing, when more than fourpressing protrusions 154 a′ of the opening and closing member 154′ areformed, the opening and closing member 154′ may open the flow path cover152 by a large number of times than the opening and closing member 154according to the first embodiment of the disclosure.

Therefore, the flow rate regulator 150′ according to the thirdembodiment of the disclosure may provide a larger amount of outside airto the dust collecting chamber 20 than that of the flow rate regulator150 according to the first embodiment of the disclosure.

As mentioned above, the amount of outside air provided to the dustcollecting chamber 20 may be variously adjusted by changing the numberof pressing protrusions 154 a′ of the opening and closing member 154′.Therefore, the optimal supply of outside air may be analyzed based onthe shape of the inside of the dust collecting chamber 20, andaccordingly, the various shapes of the opening and closing member 154′may be provided to supply the outside air into the inside of the dustcollecting chamber 20 according to the optimal supply of outside air.

Hereinafter a flow rate regulator 170 according to a fourth embodimentof the disclosure will be described. A configuration other than the flowrate regulator 170 according to the fourth embodiment of the disclosureis the same as the configuration according to the first embodiment ofthe disclosure, and thus a description thereof will be omitted.

FIG. 13 is a perspective view of a flow rate regulator of a stationaccording to a fourth embodiment of the disclosure, FIG. 14 is aschematic sectional side view illustrating a state in which the flowrate regulator of FIG. 13 closes a connecting flow path, and FIG. 15 isa schematic sectional side view illustrating a state in which the flowrate regulator of FIG. 13 opens the connecting flow path.

Accordingly,outside air may not be supplied to the dust collecting chamber 20through the connecting flow path 171.

In response to the arrangement the connecting flow path 171 and thecutout portion 172 b overlapping each other in the vertical direction bythe rotation of the flow path cover 172, the connecting flow path 171may be opened to the outside through the cutout portion 172 b.Accordingly, outside air may be supplied to the dust collecting chamber20 through the connecting flow path 171.

As the opening and closing unit 173 continues to rotate the flow pathcover 172 by the motor, the connecting flow path 171 may alternatelyoverlap with the body 172 a and the cutout portion 172 b in the verticaldirection.

The cutout portion 172 b may be formed larger than the body 172 a asneeded. The optimal supply of outside air may be analyzed based on theshape of the inside of the dust collecting chamber 20, and accordingly,the body 172 a may have various areas to supply the outside air into theinside of the dust collecting chamber 20 according to the optimal supplyof outside air.

Hereinafter a flow rate regulator 180 according to a fifth embodiment ofthe disclosure will be described. A configuration other than the flowrate regulator 180 according to the fifth embodiment of the disclosureis the same as the configuration according to the first embodiment ofthe disclosure, and thus a description thereof will be omitted.

Referring to FIG. 19, the flow rate regulator 190 may include aconnecting flow path 191 connected to the dust collecting guide 30 and ablower 193 configured to blow outside air to the connecting flow path191.

The blower 193 may include a blowing fan. The blower 193 may be drivento blow outside air into the connecting flow path 191, and thus a largeamount of outside air may flow along the connecting flow path 191 to thedust collecting guide 30 and the dust collecting chamber 20.

The blower 193 may be periodically turned on or turned off. Accordingly,the outside air may be blown to the connecting flow path 191 at apredetermined interval.

According to the blowing amount of the blower 193, the flow rateregulator 190 according to the sixth embodiment of the disclosure maygenerate a larger difference in the flow rate than the flow rateregulator 150 according to the first embodiment of the disclosure.

Therefore, it is possible to generate a large change in the flow rate ofthe inside air of the dust collecting chamber 20, thereby effectivelyremoving the foreign substances in the dust collecting chamber 20.

Hereinafter a flow rate regulator 200 according to a seventh embodimentof the disclosure will be described. A configuration other than the flowrate regulator 200 according to the seventh embodiment of the disclosureis the same as the configuration according to the first embodiment ofthe disclosure, and thus a description thereof will be omitted.

FIG. 20 is a view illustrating a state in which a flow rate regulator ofa station opens a discharge port of a dust collecting chamber accordingto a seventh embodiment of the disclosure, and FIG. 21 is a viewillustrating a state in which the flow rate regulator of the stationcloses the discharge port of the dust collecting chamber according tothe seventh embodiment of the disclosure.

Referring to FIGS. 20 and 21, the flow rate regulator 200 may include adischarge port opening and closing unit 201 configured to open and closethe discharge port 13 of the cleaner.

The discharge port opening and closing unit 201 may be configured tocover the discharge port 13 upon the docking of the cleaner 10 to thedocking station 100.

The discharge port opening and closing unit 201 may include a dischargeport cover 201 a provided in a cut annular shape.

The discharge port cover 201 a may close the discharge port 13 from theoutside in such a way that the annular discharge port cover 201 asurrounds the discharge port 13. It is appropriate that the dischargeport cover 201 a is formed with two pieces so as to cover the dischargeport 13.

However, the shape of the discharge port cover 201 a is not limitedthereto, and the discharge port cover 201 a may be provided in a shapecorresponding to the shape in which the discharge port 13 is arranged inthe cleaner 10, and the number of the discharge port cover 201 a mayvary according to the arrangement of the discharge port 13.

Thedriver (not shown) may drive the discharge port cover 201 a to allow thedischarge port cover 201 a to periodically open and close the dischargeport 13 while the suction device 130 is driven.

Particularly, the discharge port cover 201 a may include a hinge 201 bprovided to be rotatably coupled to the body housing 110. The driver(not shown) may rotate the discharge port cover 201 a about the hinge201 b.

In response to the rotation of the discharge port cover 201 a beingtoward the cleaner 10 about the hinge 201 b, the discharge port cover201 a may cover the discharge port 13 and close the discharge port 13.

By the suction device 130, a negative pressure is generated inside thedust collecting chamber 20. Upon covering the discharge port 13 by thedischarge port cover 201 a, the discharge port cover 201 a may receive asuction force through the discharge port 13, thereby more tightlycovering the discharge port 13.

In response to the rotation of the discharge port cover 201 a beingtoward the opposite side of the cleaner 10 about the hinge 201 b, thedischarge port cover 201 a may open the discharge port 13.

The driver (not shown) may drive the discharge port cover 201 a toalternately change the rotation direction of the discharge port cover201 a to allow the discharge port 13 to be periodically opened andclosed.

The flow rate regulators 150, 170, 180 and 190 according to the first tosixth embodiments may transfer the outside air to the dust collectingchamber 20 through the dust collecting guide 30 connected to the dustcollecting chamber 20, but the flow rate regulator 200 according to theseventh embodiment as illustrated in FIGS. 20 and 21 may regulate theamount of the outside air flowing into the inside of the dust collectingchamber 20 by opening or closing the discharge port 13 communicatingwith the dust collecting chamber 20.

Accordingly, the amount of air flowing into the dust collecting chamber20 may be changed at a predetermined interval and thus the flow rate ofthe air inside the dust collecting chamber 20 may be changed.

Further, although not shown in the drawings, unlike the first to sixthembodiments of the disclosure, it is not required to dock the dustcollecting guide 30 to the docking station 100.

The flow rate regulator 200 according to the seventh embodiment of thedisclosure changes the air pressure of the inside of the dust collectingchamber 20 by opening and closing the discharge port 13 withoutsupplying the outside air to the dust collecting chamber 20 through thedust collecting guide 30 as described above. Therefore, it is notrequired that the dust collecting guide 30 is docked to the dockingstation 100 to be connected to the flow rate regulator.

Therefore, a user may dock only the dust collecting chamber 20 to thedocking station 100 without separating an extension tube (not shown) orthe suction unit (not shown) of the cleaner 10 from the dust collectingguide 30.

Hereinafter a cleaning apparatus 1′ according to an eighth embodiment ofthe disclosure will be described. A configuration other than thecleaning apparatus 1′ according to the eighth embodiment of thedisclosure is the same as the configuration according to the firstembodiment of the disclosure, and thus a description thereof will beomitted.

FIG. 22 is a perspective view of a station according to an eighthembodiment of the disclosure, FIG. 23 is a perspective view of acleaning apparatus according to the eighth embodiment of the disclosure,FIG. 24 is a view illustrating some components of the station accordingto the eighth embodiment of the disclosure, and FIG. 25 is a sidesectional view of some components of the cleaning apparatus according tothe eighth embodiment of the disclosure.

As for the cleaning apparatus 1 according to the first to sixthembodiments, in order to increase the efficiency of automatic dischargeat the automatic discharge operation of the docking station 100, theflow rate regulators 150, 170, 180 and 190 may change the air pressureof the inside of the dust collecting chamber 20 by using a method ofsupplying the outside air to the dust collecting chamber 20 through thedust collecting guide 30 connected to the dust collecting chamber 20.

Accordingly, the dust collecting guide 30 communicating with the dustcollecting chamber 20 is also docked to the docking station 100 togetherwith the dust collecting chamber 20, and the docking station 100 may beconfigured to allow the outside air to selectively flow into the dustcollecting guide 30 by the flow rate regulators 150, 170, 180 and 190upon the docking of the dust collecting guide 30 to the docking station100.

According to the first to sixth embodiments of the disclosure, in orderto automatically discharge the foreign substances collected in the dustcollecting chamber 20 by docking the cleaner 10 to the docking station100, a user may separate the extension tube or the suction unit, whichmay be coupled to the dust collecting guide 30, and dock the dustcollecting guide 30 to the docking station 100.

At this time, it may be inconvenient for a user to separate theextension tube or the suction unit, which may be coupled to the dustcollecting guide 30, and it may lead to reduction in usability. However,the cleaning apparatus 1′ according to the eighth embodiment of thedisclosure may dock the cleaner 10 to the docking station 100 and allowthe collected foreign substances of the dust collecting chamber 20 to beautomatically discharged even when an extension tube 17 or a suctionunit 18 is coupled to the dust collection guide 30 of the cleaner 10.

That is, as for the cleaning apparatus 1 according to the firstembodiment, the automatic discharge of the docking station 100 may beeffectively performed only when both of the dust collecting chamber 20and the dust collecting guide 30 of the cleaner 10 are docked to thedocking station 100. However, as for the cleaning apparatus 1′ accordingto the eighth embodiment, the automatic discharge of a docking station300 may be effectively performed as long as the dust collecting chamber20 of the cleaner 10 is docked to the docking station 300.

Accordingly, referring to FIGS. 22 to 25, the docking station 300 mayinclude a docking housing 340 to which the dust collecting chamber 20 isdocked, without a component to which the dust collecting guide 30 isdocked. Therefore, in response to docking of the cleaner 10 to thedocking station 300, the extension tube 17 and the suction unit 18 maybe mounted on the docking station 300 in a state of being coupled to thedust collecting guide 30.

The extension tube 17 of the cleaner 10 may be provided to have a longaxis extending in one direction.

The dust collecting chamber 20 may include a cylindrical shape includingthe long axis extending in one direction. Although it will be describedlater, the dust collecting chamber 20 may be configured to separateforeign substances introduced into the dust collecting chamber 20through centrifugation. Accordingly, the dust collecting chamber 20 maybe provided in an approximately cylindrical shape.

The dust collecting chamber 20 and the extension tube 17 may be coupledto the cleaner 10 in such a way that the long axis of the cylindricalshape of the dust collecting chamber 20 and the long axis of theextension tube 17 extend in approximately corresponding directions.

The docking station 300 may include a body housing 310 and the dockinghousing 340 described above. A charger 320 configured to charge abattery 16 of the cleaner 10 upon the docking of the cleaner 10 to thedocking station 300 may be provided above the body housing 310.

By including a suction device 330, the docking station 300 may dischargedust collected in the dust collecting chamber 20 from the dustcollecting chamber 20.

The suction device 330 may be arranged inside the body housing 310.

The body housing 310 may be provided to have a long axis extending inone direction. It is appropriate that the long axis of the body housing310 extends in the vertical direction.

The docking station 300 may include a collector 350 in which foreignsubstances discharged from the dust collecting chamber 20 are collected.The collector 350 may be arranged in the body housing 310. The collector350 may be arranged above the suction device 330.

The docking station 300 may include an intake flow path 341 configuredto connect the docking housing 340 to the collector 350 and configuredto allow foreign substances, which are discharged from the dustcollecting chamber 20, to be suctioned to the collector 350 through thedocking housing 340.

The docking housing 340 may include a seating portion 342 configured tocommunicate with the intake flow path 341 and on which the dustcollecting chamber 20 is mounted.

The seating portion 342 may be provided to be opened toward an upperside with respect to the long axis of the body housing 310.

The seating portion 342 may correspond to a space opened to the outsidefrom the docking housing 340 and the seating portion 342 may be providedto allow the dust collecting chamber 20 to be inserted thereto in thevertical direction and to be seated thereon.

Upon seating the dust collecting chamber 20 on the seating portion 342,docking of the cleaner 10 to the docking station 300 may be completed.

The dust collecting chamber 20 may be docked to the seating portion 342in a direction in which the long axis of the body housing 310 extends.

The dust collecting chamber 20 may be docked to the seating portion 342in a direction in which the long axis of the cylindrical shape of thedust collecting chamber 20 extends.

Accordingly, upon the docking of the dust collecting chamber 20 to thedocking station 300, the long axis of the body housing 310 and the longaxis of the extension tube 17 may be provided so as to facesubstantially in a corresponding direction. This is because, asdescribed above, the dust collecting chamber 20 and the extension tube17 may be coupled to the cleaner 10 in such a way that the long axis ofthe cylindrical shape of the dust collecting chamber 20 and the longaxis of the extension tube 17 extend in approximately correspondingdirections.

Although not shown in the drawings, the switch unit, and the pressingprotrusion described in the first embodiment of the disclosure may bearranged inside the seating portion 342.

Therefore, upon seating the dust collecting chamber 20 on the seatingportion 342, the dust collecting chamber door 21 may be opened, and thecontroller (not shown) may confirm a state in which the dust collectingchamber 20 is docked to the docking station 300, through the switchunit.

A multi-cyclone (e.g., a multi-cyclone 52) may be arranged inside thedust collecting chamber 20. The dust collecting chamber 20 may beprovided to allow the foreign substances to be collected in the lowerside of the multi-cyclone. Accordingly, upon opening of the dustcollecting chamber door 21, the foreign substance collected in the dustcollecting chamber 20 may be easily discharged to the seating portion342.

The intake flow path 341 may be connected to the collector 350 from thedocking housing 340 by penetrating through the body housing 310.However, the disclosure is not limited thereto, and the docking housing340 and the body housing 310 may be integrally formed with each other.In this case, the intake flow path 341 may be arranged in the bodyhousing 310 and thus the inside of the seating portion 342 and thecollector 350 may communicate with each other.

The intake flow path 341 may transfer the air flow generated by thesuction device 330 to the dust collecting chamber 20. That is, theintake air flow generated by the suction device 33 is transferred intothe dust collecting chamber 20 along the intake flow path 341 and theseating portion 342 through the collector 350. The foreign substance inthe dust collecting chamber 20 may be discharged from the dustcollecting chamber 20 to the seating portion 342 according to the airflow by the intake air flow, and then collected in the collector 350through the intake flow path 341.

The collector 350 may include a collector housing 351. The collectorhousing 351 may form a first inner space 352 therein. The first innerspace 352 may be opened to the outside by a first cover (not shown).

The first cover (not shown) may open and close the collector housing 351to allow the first inner space 352 to be opened to the outside bypassing through the body housing 310.

The collector 350 may include a first connector 353 arranged at an upperside of the collector 350 and connected to the first inner space 352 andthe intake flow path 341.

The collector 350 may include a second connector 354 connected to thesuction device 330 through the flow rate regulator 210, which isdescribed later, and arranged below the collector 350.

A collection bag 355 may be arranged in the first inner space 352 tocollect foreign substances introduced through the first connector 353along the intake flow path 341.

The collection bag 355 may be formed of a material through which air istransmitted and foreign substances are not, and thus the collection bag355 may collect foreign substances introduced into the collector 350from the dust collecting chamber 20.

An upper end of the first connector 353 may be connected to the intakeflow path 341 and a lower end of the first connector 353 may beconnected to the collection bag 355. The collection bag 355 may beremovably coupled to the lower end of the first connector 353.

The intake air flow generated by the suction device 330 may flow intothe first inner space 352 through the first connector 353 and thecollection bag 355 and then may be discharged to the outside of thecollector 350 through the second connector 354.

The suction device 330 may include a suction fan 331 and a suctiondevice housing 332 forming a second inner space 333 in which the suctionfan 331 is arranged.

The second inner space 333 may be provided to be opened and closed by asecond cover 335 arranged in the body housing 310. The second cover 335may be configured to discharge air suctioned by the suction fan 331.

A third connector 334 configured to supply the intake air flow generatedby the suction fan 331 to the dust collecting chamber 20 may be providedon an upper side of the suction device 330.

The intake air flow generated by the suction fan 331 may be supplied tothe dust collecting chamber 20 from the second inner space 333 by movingalong the collector 350 and the intake flow path 341 through the thirdconnector 334.

The docking station 300 may include a flow rate regulator 210 configuredto selectively change an amount of intake air flow supplied to the dustcollecting chamber 20.

The flow rate regulator 210 may be arranged inside the body housing 310.The flow rate regulator 210 may be arranged between the collector 350and the suction device 330. Particularly, the flow rate regulator 210may be connected to the second connector 354 and the third connector334.

The flow rate regulators 150, 170, 180, 190, and 200 according to thefirst to seventh embodiments may change the air pressure inside the dustcollecting chamber 20 by additionally supplying the outside air orstopping supplying the outside air, while maintaining the intake airflow supplied from the suction device at a predetermined state.

However, the flow rate regulator 210 according to the eighth embodimentmay change the air pressure inside the dust collecting chamber 20 bychanging the amount of intake air flow supplied to the dust collectingchamber 20.

That is, the flow rate regulator 210 may selectively open and close theconnecting flow path 212 communicating with the suction device 330 andthe dust collecting chamber 20, which will be described later, so as tosupply or block the intake air flow generated by the suction device 330,thereby changing the air pressure inside the dust collecting chamber 20.

Accordingly, the loss of the air flow amount supplied to the dustcollecting chamber 20 is reduced in comparison with the flow rateregulator 150, 170, 180, 190, and 200 according to the first to seventhembodiments, and thus automatic discharge may be performed moreefficiently.

That is, the flow rate regulators 150, 170, 180, 190, and 200 of thefirst to seventh embodiments may be configured to periodically supplythe outside air to the dust collecting chamber 20 and thus the amount ofintake air flow may be lost as much as the outside air being supplied tothe dust collecting chamber 20.

However, the flow rate regulator 210 of the eighth embodiment may notadditionally supply the outside air to the dust collecting chamber 20,and thus there is no intake air flow lost inside the dust collectingchamber 20 caused by the supply of the outside air. Therefore, the flowrate regulator 210 of the eighth embodiment may change the air pressureinside the dust collecting chamber 20 more efficiently than the flowrate regulators 150, 170, 180, 190, and 200 of the first to seventhembodiments.

As mentioned above, the flow rate regulator 210 may be arranged betweenthe collector 350 and the suction device 330. However, the disclosure isnot limited thereto, and the flow rate regulator 210 may be arrangedbetween the collector 350 and the intake flow path 341.

However, in response to the arrangement of the flow rate regulator 210being placed between the collector 350 and the intake flow path 341, theintake air flow generated by the suction device 330 may flow into theflow rate regulator 210 through the collector 350 and thus some of theintake air flow supplied to the dust collecting chamber 20 may be lost.

In addition, in response to the arrangement the flow rate regulator 210being placed between the collector 350 and the intake flow path 341, aircontaining foreign substance discharged from the dust collecting chamber20 may pass through the flow rate regulator 210, and thus it may causethe difficulty in the sanitation.

Therefore, it is appropriate that the flow rate regulator 210 isarranged between the suction device 330 and the collector 350.

That is, the intake air flow generated by the suction device 330 may besupplied to the dust collecting chamber 20 by passing through the flowrate regulator 210, the collector 350, the intake flow path 341, and theseating portion 342 sequentially.

Together with the foreign substance collected in the dust collectingchamber 20, the intake air flow supplied to the dust collecting chamber20 may move by sequentially passing through the seating portion 342, theintake flow path 341 and the collector 350.

In the collector 350, the foreign substance discharged from the dustcollecting chamber 20 may be collected, and the air separated from theforeign substance may be discharged to the outside of the body housing310 through the flow rate regulator 210 and the suction device 330. Theflow rate regulator 210 will be described later in detail.

Hereinafter a collector according to a ninth embodiment of thedisclosure will be described. A configuration other than the collector350 according to the ninth embodiment of the disclosure is the same asthe configuration according to the eighth embodiment of the disclosure,and thus a description thereof will be omitted.

The collection bag 355 may be arranged in the collector 350 according tothe eighth embodiment, and thus the foreign substances discharged fromthe dust collecting chamber 20 may be collected in the collection bag355.

When the collection bag 355 is fully filled with the foreign substance,a user may separate the collection bag 355 from the first connector 353,discharge the foreign substance collected in the collection bag 355, andthen couple the collection bag 355 to the first connector 353.

The disclosure is not limited thereto, and the collector 350 accordingto the ninth embodiment may include an additional dust collectingchamber 356 arranged in the first inner space 352. The inner space ofthe additional dust collecting chamber 356 may be provided to be largerthan the inner space of the dust collecting chamber 20.

The additional dust collecting chamber 356 may include a multi-cyclone357. Accordingly, air containing the foreign substance introduced intothe collector 350 through the first connector 353 may flow into theadditional dust collecting chamber 356 and the foreign substance may beremoved through the multi-cyclone 357 and then the air, from which theforeign substance is removed, may flow into the flow rate regulator 210through the second connector 354.

An upper side of the additional dust collecting chamber 356 maycommunicate with the first connector 353 and a lower side of theadditional dust collecting chamber 356 may communicate with the secondconnector 354. The additional dust collecting chamber 356 may beremovably coupled to the first connector 353 and the second connector354.

Therefore, the air introduced through the first connector 353 may bedischarged to the second connector 354 by passing through themulti-cyclone 357. While the air passes through the multi-cyclone 357,the foreign substances discharged from the dust collecting chamber 20may be collected in the additional dust collecting chamber 356.

Hereinafter the flow rate regulator 210 according to the eighthembodiment of the disclosure will be described in detail.

FIG. 27 is a perspective view of a flow rate regulator of the stationaccording to the eighth embodiment of the disclosure, FIG. 28 is a viewillustrating a state in which the flow rate regulator of the stationopens a connecting flow path according to the eighth embodiment of thedisclosure, and FIG. 29 is a view illustrating a state in which the flowrate regulator of the station closes the connecting flow path accordingto the eighth embodiment of the disclosure.

Referring to FIG. 27, the flow rate regulator 210 may include a flowpath housing 211 forming a connecting flow path 212 connecting thesuction device 330 to the collector 350.

Particularly, the connecting flow path 212 may be configured to connectthe second connector 354 to the third connector 334. Accordingly, thesuction device 330 and the collector 350 may communicate with each otherthrough the connecting flow path 212, and the intake air flow generatedby the suction device 330 may move to the collector 350 through theconnecting flow path 212.

An upper end 211 a of the flow path housing 211 may be connected to thesecond connector 354 and a lower end 211 b of the flow path housing 211may be connected to the third connector 334.

The connecting flow path 151 disclosed in the first to sixth embodimentsmay be connected to the dust collecting guide 30 and configured to flowthe outside air to the dust collecting guide 30, but the connecting flowpath 212 of the eighth embodiment may connect the suction device 330 tothe collector 350.

The flow rate regulator 210 may include a flow path valve 213 arrangedon the connecting flow path 212 and configured to open and close theconnecting flow path 212 to regulate the intake air flow in theconnecting flow path 212.

The flow rate regulator 210 may include a drive motor 214 configured todrive the flow path valve 213.

A rotary shaft 215 may be arranged on the rotation axis of the drivemotor 214. The flow path valve 213 may be coupled to the rotary shaft215 to be rotated in one direction or the opposite direction.

The flow path valve 213 may be configured to open or close theconnecting flow path 212 while rotating on the connecting flow path 212.

Particularly, the flow path valve 213 may have a cylindrical shapeincluding the cutout portion 213 a and the body 213 b. A central axis ofthe cylindrical shape may be provided in a direction corresponding tothe extending direction of the rotary shaft 215.

The cutout portion 213 a may be provided to be cut at a predetermineddistance in the circumferential direction of the cylindrical shape andto extend in the extending direction of the cylindrical shape.

The cutout portion 213 a may be provided in a pair symmetrical about acentral axis of a cylindrical shape.

As mentioned above, the flow path valve 213 may be configured to rotateon the connecting flow path 212. The flow path valve 213 may be rotatedto one direction due to the drive of the drive motor 214. In therotation of the flow path valve 213 in one direction, when the flow pathvalve 213 is positioned to allow a direction D, in which the intake airflow moves, to face the pair of cutout portion 213 a on the connectingflow path 121, the intake air flow may move inside the connecting flowpath 212 by passing through the cutout portion 213 a.

That is, referring to FIG. 28, it is assumed that a position of the flowpath valve 213, in which the pair of cutout portions 213 a faces theflow direction D of the intake air flow during the rotation of the flowpath valve 213, is an open position 213 (o). In response to the openposition 213 (o) of the flow path valve 213 during the rotation, theintake air flow may be supplied to the dust collecting chamber 20.

In the rotation of the flow path valve 213 in one direction, when theflow path valve 213 is positioned to allow the direction D, in which theintake air flow moves, to face the body 213 b on the connecting flowpath 121, the movement of the intake air flow may be blocked by the body213 b. The intake air flow may not move from the suction device 330 tothe collector 350 by being blocked by the body 213 b and thus the intakeair flow may be not supplied to the dust collecting chamber 20.

That is, referring to FIG. 29, it is assumed that a position of the flowpath valve 213, in which the body 213 b faces the flow direction D ofthe intake air flow during the rotation of the flow path valve 213, is aclosed position 213 (c). In response to the closed position 213 (c) ofthe flow path valve 213 during the rotation, the intake air flow may notbe supplied to the dust collecting chamber 20.

The cutout portion 213 a and the body 213 b may be sequentially arrangedin the direction D in which the intake air flow flows as the drive motor214 is rotated in one direction. Accordingly, the flow path valve 213may sequentially open and close the connecting flow path 212.

According to the opening and closing of the flow path valve 213, theintake air flow may be supplied to the dust collecting chamber 20 or thesupply of the intake air flow may be stopped. Accordingly, the airpressure inside the dust collecting chamber 20 may be changed.

Upon opening of the flow path valve 213, the intake air flow may besupplied to the dust collecting chamber 20 and thus the air pressureinside the dust collecting chamber 20 may decrease. Upon closing of theflow path valve 213, the supply of the intake air flow may be stoppedand thus the air pressure inside the dust collecting chamber 20 mayincrease.

As mentioned, the flow path valve 213 may periodically open and closethe connecting flow path 212 and thus the air pressure inside the dustcollecting chamber 20 may decrease and increase. Accordingly, the flowdirection of the air inside the dust collecting chamber 20 may bevariously generated.

Upon seating of the dust collecting chamber 20 on the seating portion342, the docking of the cleaner 10 may be detected by a switch unit (notshown), and thus the flow rate regulator 210 may be driven.

The controller (not shown) may control the drive motor 214 to allow theflow path valve 213 to be arranged at the open position 213 (o) for apredetermined period of time. After the predetermined period of timeelapses, the controller (not shown) may control the drive motor 214 toallow the flow path valve 213 to be arranged in the closed position 213(c) for another predetermined period of time.

That is, the controller (not shown) may control the drive motor 214 toallow the flow path valve 213 to be sequentially arranged at the openposition 213 (o) and the closed position 213 (c) at a predeterminedinterval.

It is appropriate that the controller (not shown) may control the drivemotor (not shown) to allow a period of time in which the flow path valve213 is in the open position 213 (o) to be longer than a period of timein which the flow path valve 213 is arranged in the closed position 213(c). This is to increase the amount of intake air flow supplied to thedust collecting chamber 20.

As mentioned above, the flow rate regulator 210 may selectively changethe amount of intake air flow supplied to the dust collecting chamber20. As the intake air flow amount supplied to the dust collectingchamber 20 is changed, the air pressure inside the dust collectingchamber 20 may be changed according to the intake air flow amount, andaccordingly, the flow of air in the dust collecting chamber 20 may bevariously generated. The suction efficiency can be increased.

However, the disclosure is not limited thereto, and the controller (notshown) may control the air flow amount by changing the size of a regionfacing the flow direction D of the intake air flow in the cutout portion213 a of the flow path valve 213.

Because the flow path valve 213 is configured to be arranged at anymiddle position between the open position 213 (o) and the closedposition 213 (c) using the rotation of the drive motor 214, it ispossible to change the intake air flow amount, which is supplied to thedust collecting chamber 20, to be less than that when the flow pathvalve 213 is in the open position 213 (o) and it is possible to changethe intake air flow amount, which is supplied to the dust collectingchamber 20, to be greater than that when the flow path valve 213 is inthe closed position 213 (c).

That is, the flow rate regulator 210 may vary the intake air flow amountsupplied to the dust collecting chamber 20 by the rotation of the flowpath valve 213, and accordingly, the air pressure inside the dustcollecting chamber 20 may be variously changed.

In addition, the above-mentioned description is not limited to theeighth embodiment, and thus it is possible to regulate the intake airflow amount by using components of the flow path covers 152, 172, and182 according to the first to fifth embodiments. That is, by arrangingthe flow rate regulators 150, 170, and 180 according to the first tofifth embodiments in the collector 350 and the suction device 330, andby arranging the flow path covers 152, 172, and 182 on the connectingflow path 212, it is possible to regulate the amount of intake air flowsupplied to the dust collecting chamber 20.

Hereinafter a cleaning apparatus 1″ according to a tenth embodiment ofthe disclosure will be described. A configuration other than thecleaning apparatus 1″ according to the tenth embodiment of thedisclosure is the same as the configuration of the cleaning apparatus 1′according to the eighth embodiment of the disclosure, and thus adescription thereof will be omitted.

FIG. 30 is a perspective view of the docking station 1″ according to atenth embodiment of the disclosure, FIG. 31 is a view illustrating astate in which a dust collecting chamber of a cleaner is docked to adocking station according to the tenth embodiment of the disclosure,FIG. 32 is an exploded perspective view of the docking station accordingto the tenth embodiment of the disclosure and FIG. 33 is a sidecross-sectional view of the docking station according to the tenthembodiment of the disclosure.

In the same manner as the cleaning apparatus 1′ according to the eighthembodiment, a cleaning apparatus 1″ according to the tenth embodiment ofthe disclosure may automatically discharge the collected substances bychanging the intake air flow supplied to a dust collecting chamber 20 ofa cleaner 10.

That is, as for the cleaning apparatus 1 according to the firstembodiment, the automatic discharge of the docking station 100 may beeffectively performed only when both of the dust collecting chamber 20and the dust collecting guide 30 of the cleaner 10 are docked to thedocking station 100. However, as for the cleaning apparatus 1′ accordingto the eighth embodiment, the automatic discharge of the docking station300 may be effectively performed as long as the dust collecting chamber20 of the cleaner 10 is docked to the docking station 300.

Further, the cleaning apparatus 1″ according to the tenth embodiment ofthe disclosure separates a dust collecting chamber 50 from the cleaner10 and then dock only the dust collecting chamber 50 to the dockingstation 400, thereby automatically discharging the dust inside the dustcollecting chamber 50.

Therefore, a user may separate only the dust collecting chamber 50 fromthe cleaner 10 and dock the dust collecting chamber 50 to the dockingstation 400 without docking the entire cleaner 10 to the docking station400. Accordingly, it is possible to make the size of the docking station400 miniaturized, and it is possible to automatically discharge the dustof the dust collecting chamber 50 by simply separating the dustcollecting chamber 50.

Referring to FIGS. 30 to 33, the docking station 400 may include a bodyhousing 410 and a docking housing 440 configured to allow the dustcollecting chamber 50 to be docked thereto without a componentconfigured to allow the dust collecting guide 30 to be docked thereto.

The body housing 410 may include a panel 412 arranged on the front ofthe body housing 410 and configured to be removable from the bodyhousing 410. Alternatively, the panel 412 may be arranged on a sidesurface or a rear surface of the body housing 410 as well as the frontsurface of the body housing 410, and configured to be removable from thebody housing 410.

As the panel 412 is separated from the body housing 410, a user can openthe collector 450, which is described later, and easily replace a dustbag 455 arranged in the collector 450.

By including a suction device 430, the docking station 400 may dischargedust collected in the dust collecting chamber 50 from the dustcollecting chamber 50.

The suction device 430 may be arranged inside the body housing 410.

The docking station 400 may include the collector 450 in which foreignsubstances discharged from the dust collecting chamber 50 are collected.The collector 450 may be arranged inside the body housing 410. Thecollector 450 may be arranged above the suction device 430.

The docking station 400 may include an intake flow path 441 configuredto connect the docking housing 440 to the collector 450, and configuredto allow foreign substances, which are discharged from the dustcollecting chamber 50, to be suctioned into the collector 450 throughthe docking housing 440.

The docking housing 440 may include a seating portion 442 configured tocommunicate with the intake flow path 441 and on which the dustcollecting chamber 50 is mounted.

The seating portion 442 may be provided to be opened toward an upperside with respect to the long axis of the body housing 410.

The seating portion 442 may correspond to a space opened to the outsidefrom the docking housing 440, and the seating portion 442 may beprovided to allow the dust collecting chamber 50 to be inserted theretoin the vertical direction and to be seated thereon.

Upon seating the dust collecting chamber 50 on the seating portion 442,docking of the cleaner 10 to the docking station 400 may be completed.

The dust collecting chamber 50 may be docked to the seating portion 442in a direction in which the long axis of the body housing 410 extends.

The dust collecting chamber 50 may be docked to the seating portion 442in a direction in which the long axis of the cylindrical shape of thedust collecting chamber 50 extends.

Accordingly, upon the docking of the dust collecting chamber 50 to thedocking station 400, the long axis of the body housing 410 and the longaxis of the dust collecting chamber 50 may be provided so as to face ina substantially corresponding direction.

Although not shown in the drawings, the switch unit described in thefirst embodiment of the disclosure may be arranged inside the seatingportion 442.

Therefore, upon seating the dust collecting chamber 50 on the seatingportion 442, the controller (not shown) may confirm a state in which thedust collecting chamber 50 is docked to the docking station 400, throughthe switch unit.

Multi-cyclone 52 may be arranged inside the dust collecting chamber 50.The dust collecting chamber 50 may be provided to allow the foreignsubstances to be collected in a lower side 52 a of the multi-cyclone 52.The dust collecting chamber 50 may include a first dust collector 50 aconfigured to collect foreign substances which are primarily collectedand have a relatively large size, and a second dust collector 50 bconfigured to collect foreign substance, which are collected by themulti-cyclone 52 and have a relatively small size.

The first dust collector 50 a and the second dust collector 50 b may beopened to the outside upon the opening of a dust collecting chamber door51.

Accordingly, upon opening of the dust collecting chamber door 51arranged in the lower side of the dust collecting chamber 50, theforeign substance collected in the dust collecting chamber 50 may beeasily discharged to the seating portion 442.

The intake flow path 441 may be connected to the collector 450 from thedocking housing 440 by penetrating through the body housing 410.However, the disclosure is not limited thereto, and the docking housing440 and the body housing 410 may be integrally formed with each other.

The intake flow path 441 may transfer the air flow generated by thesuction device 430 to the dust collecting chamber 50. That is, theintake air flow generated by the suction device 430 is transferred intothe dust collecting chamber 50 along the intake flow path 441 and theseating portion 442 through the collector 450. The foreign substance inthe dust collecting chamber 50 may be discharged from the dustcollecting chamber 50 to the seating portion 442 according to the airflow by the intake air flow, and then collected in the collector 450through the intake flow path 441.

The collector 450 may include a collector housing 451. The collectorhousing 451 may form an inner space.

The collector 450 may include a collector cover 452. The collector cover452 may be arranged on the front surface of the collector housing 451.The collector cover 452 may open and close the collector housing 451 toallow the inside of the collector 450 to be opened to the outside in astate in which the panel 412 is separated.

The collector 450 may include a dust bag 455 arranged in the inner spaceof the collector 450 and configured to collect foreign substancesintroduced through the intake flow path 441.

The dust bag 455 may be formed of a material through which air istransmitted and foreign substances are not, and thus the dust bag 455may collect foreign substances introduced into the collector 450 fromthe dust collecting chamber 50.

The dust bag 455 may be directly connected to the intake flow path 441,and the dust bag 455 may be separable from the collector 450.

When the docking station 400 is driven to collect foreign substance inthe dust bag 455, a user can separate the panel 412 and open thecollector cover 452 to separate the dust bag 455 from the collector 450,thereby discharging the foreign substances collected in the dockingstation 400.

Although not shown in the drawings, the collector 450 may include anadditional dust collecting chamber (not shown) in addition to the dustbag 455 as in the ninth embodiment. An inner space of the additionaldust collecting chamber (not shown) is provided to be larger than aninner space of the dust collecting chamber 50, and the additional dustcollecting chamber (not shown) may collect fine foreign substance byincluding a multi-cyclone in the same manner as the dust collectingchamber 50.

The suction device 430 may include a suction fan 431 and a suctiondevice housing 432 forming the inner space in which the suction fan 431is arranged.

The suction device housing 432 may include a suction device cover 435arranged in the body housing 410 and configured to open and close theinside of the suction device housing 432. The suction device cover 435may be configured to allow air suctioned by the suction fan 431 to bedischarged.

The intake air flow generated by the suction fan 431 may be supplied tothe dust collecting chamber 50 from the inner space of the suctiondevice housing 432 through the collector 450 and the intake flow path441.

The docking station 400 may include a flow rate regulator 220 configuredto selectively change an amount of intake air flow supplied to the dustcollecting chamber 50.

The flow rate regulator 220 may be arranged inside the body housing 410.The flow rate regulator 220 may be arranged between the collector 450and the suction device 430. Particularly, the flow rate regulator 220may be connected to a flow path to which the collector 450 and thesuction device 430 are connected.

However, the disclosure is not limited thereto, and the flow rateregulator 220 may be arranged between the collector 450 and the suctionflow path 441.

Hereinafter the flow rate regulator 220 according to the tenthembodiment of the disclosure will be described in detail.

FIG. 34 is an exploded perspective view of a flow rate regulatoraccording to the tenth embodiment of the disclosure, FIG. 35 is a viewillustrating a state in which the flow rate regulator of FIG. 34 closesa connecting flow path, and FIG. 36 is a view illustrating a state inwhich the flow rate regulator of FIG. 34 opens the connecting flow path.

Referring to FIGS. 34 to 36, the flow rate regulator 220 may include aflow path housing 221 forming a connecting flow path 222 configured toconnect the collector 450 to the suction device 430.

Particularly, the connecting flow path 222 may be configured to connectthe collector 450 to the suction device 430 and to allow air to flow.Accordingly, the collector 450 and the suction device 430 maycommunicate with each other through the connecting flow path 222, andthe intake air flow generated by the suction device 430 may move to thecollector 450 through the connecting flow path 222.

The connecting flow path 151 disclosed in the first to sixth embodimentsmay be connected to the dust collecting guide 30 and configured to allowthe outside air to flow to the dust collecting guide 30, but theconnecting flow path 212 according to the eighth embodiment and theconnecting flow path 222 according to the tenth embodiment may beconfigured to connect the suction device 430 to the collector 450.

The flow rate regulator 220 may include a flow path valve 223 arrangedon the connecting flow path 222 and configured to open and close theconnecting flow path 222 to regulate the intake air flow in theconnecting flow path 222.

The flow rate regulator 220 may include a drive motor 224 configured toallow the flow path valve 223 to open and close the connecting flow path222 by using the rotation thereof.

A rotating member 225 may be arranged on a rotation axis of the drivemotor 224. The rotating member 225 may be provided in a disk shape andmay be rotated about the rotation axis of the drive motor 224.

A shaft 226 may be arranged on one side of the rotating member 225. Theshaft 226 may be arranged on the outside of the rotation axis of therotating member 225. Accordingly, the shaft 226 may revolve around therotation axis of the drive motor 224 upon driving of the drive motor224.

The flow path valve 223 may include a slit 229 into which the shaft 226is inserted.

The slit 229 may allow the flow path valve 223 to reciprocate in a firstdirection A in conjunction with the revolution of the shaft 226 insertedinto the slit 229.

The first direction A may be a left-right direction or a front-reardirection perpendicular to the vertical direction in which theconnecting flow path 222 extends.

The shaft 226 may move the slit 229 to the first direction A and adirection opposite to the first direction A while the shaft 226reciprocates in a second direction B perpendicular to one direction inthe slit 229.

The second direction B is a direction perpendicular to the firstdirection A and the vertical direction in which the connecting flow path222 extends. Therefore, when the first direction A is the left and rightdirection, the second direction B may be the front and rear direction,and when the first direction A is the front and rear direction, thesecond direction B may be the left and right direction.

The flow path valve 223 may include a plate 228 configured to performtranslational motion in the first direction A in conjunction with theslit 229, and configured to selectively open and close the connectingflow path 222 through translational motion.

The plate 228 may be integrally formed with the slit 229. Therefore, inresponse to the movement of the slit 229 in the first direction A, theplate 228 may be moved in the first direction A together with the slit229.

The plate 228 may be provided to reciprocate on the connecting flow path222.

In response to the rotation of the shaft 226 in one direction by therotation of the drive motor 224, the plate 228 and the slit 229 may bemoved in the first direction A and then translated in the oppositedirection of the first direction A in conjunction with the rotation ofthe shaft 226.

That is, in response to a single revolution of the shaft 226, the plate228 may reciprocate once in the first direction A. In response to thecompletion of the single revolution of the shaft 226, the plate 228 mayopen the connecting flow path 222 once and close the connecting flowpath 222 once.

It may be assumed that a starting position of the shaft 226 in therevolution of the shaft 226 is a first position 226A and a return pointcorresponding to an intermediate position during the revolution of theshaft 226 is a second position 226B. In response to the first position226A of the shaft 226, the flow path valve 223 may open the connectingflow path 222, and in response to the second position 226B of the shaft226, the flow path valve 223 may close the connecting flow path 222.

Referring to FIG. 35, when the shaft 226 revolves in one direction andmoves from the first position 226A to the second position 226B, the slit229 may be pressed in the first direction A and the plate 228 may bearranged on the connecting flow path 222. At this time, the intake airflow may be blocked by the plate 228. The intake air flow may be blockedby the plate 228 and thus the intake air flow may not flow from thesuction device 430 to the collector 450. Therefore, the intake air flowmay not be supplied to the dust collecting chamber 50.

That is, it may be assumed that when the plate 228 is placed on theconnecting flow path 222 while the flow path valve 223 reciprocates inthe first direction A in conjunction with the shaft 226, a position ofthe flow path valve 223 is a closed position 223A. In response to theclosed position 223A of the flow path valve 223 during the reciprocatingmotion, the intake air flow may not be supplied to the dust collectingchamber 50.

In contrast, referring to FIG. 36, when the shaft 226 continues torevolve in one direction and moves from the second position 226B to thefirst position 226A, the slit 229 may be pressed in an oppositedirection of the first direction A and the plate 228 may be arranged onthe outside of the connecting flow path 222. At this time, the intakeair flow may flow along the connecting flow path 222 without thelimitation. The intake air flow may flow from the suction device 430 tothe collector 450 without the limitation of the plate 228, and thus theintake air flow may be supplied to the dust collecting chamber 50.

That is, it may be assumed that when the plate 228 is placed on theoutside of the connecting flow path 222 while the flow path valve 223reciprocates in the first direction A in conjunction with the shaft 226,a position the flow path valve 223 is an open position 223B. In responseto the open position 223B of the flow path valve 223 during thereciprocating motion, the intake air flow may be supplied to the dustcollecting chamber 50.

According to the opening and closing of the flow path valve 223, theintake air flow may be supplied to the dust collecting chamber 50 or thesupply of the intake air flow may be stopped. Accordingly, the airpressure inside the dust collecting chamber 50 may be changed.

When the intake air flow is supplied to the dust collecting chamber 50upon the opening of the flow path valve 223, the air pressure inside thedust collecting chamber 50 may decrease, and when the supply of theintake air flow is stopped upon the closing of the flow path valve 223,the air pressure inside the dust collecting chamber 50 may increase.

As mentioned, the flow path valve 223 may periodically open and closethe connecting flow path 222 and thus the air pressure inside the dustcollecting chamber 50 may decrease and increase. Accordingly, the flowdirection of the air inside the dust collecting chamber 50 may vary.

When the dust collecting chamber 50 is seated on the seating portion442, the docking of the dust collecting chamber 50 may be detected by aswitch unit (not shown), and thus the flow rate regulator 220 may bedriven.

The controller (not shown) may control the drive motor 224 to allow theflow path valve 223 to be arranged at the open position 213B for apredetermined period of time. That is, the shaft 226 may be arranged inthe first position 226A without the rotation.

After the predetermined period of time elapses, the controller (notshown) may control the drive motor 224 to allow the flow path valve 223to be arranged in the closed position 223B for another predeterminedperiod of time.

That is, the controller (not shown) may control the drive motor 224 toallow the flow path valve 223 to be sequentially arranged at the openposition 223A and the closed position 223B at a predetermined interval.

It is appropriate that the controller (not shown) may control the drivemotor (not shown) to allow a period of time in which the flow path valve223 is in the open position 223A to be longer than a period of time inwhich the flow path valve 223 is arranged in the closed position 223B.This is to increase the amount of intake air flow supplied to the dustcollecting chamber 50.

As mentioned above, the flow rate regulator 220 may selectively changethe amount of intake air flow supplied to the dust collecting chamber50. As the intake air flow amount supplied to the dust collectingchamber 50 is changed, the air pressure inside the dust collectingchamber 50 may be changed according to the intake air flow amount, andaccordingly, the flow of air in the dust collecting chamber 50 may bevariously generated. The suction efficiency may be increased.

However, the disclosure is not limited thereto, and the controller (notshown) may control the air flow amount by changing the size of a regionin which the plate 228 of the flow path valve 223 closes the connectingflow path 222.

Because the flow path valve 223 is configured to be arranged at anymiddle position between the open position 223A and the closed position223B using the rotation of the drive motor 224, it is possible to changethe intake air flow amount, which is supplied to the dust collectingchamber 50, to be less than that when the flow path valve 223 is in theopen position 223A and it is possible to change the intake air flowamount, which is supplied to the dust collecting chamber 50, to begreater than that when the flow path valve 223 is in the closed position223B.

That is, the flow rate regulator 220 may vary the amount of intake airflow supplied to the dust collecting chamber 50 by the reciprocatingmotion of the flow path valve 223, and accordingly, the air pressureinside the dust collecting chamber 50 may be variously changed.

In addition, the above mentioned description is not limited to the tenthembodiment, and thus it is possible to regulate the intake air flowamount by using components of the flow path covers 152, 172, and 182according to the first to fifth embodiments and components of the flowpath valve 213 according to the eighth embodiment. That is, by arrangingthe flow rate regulators 150, 170, 180 and 210 according to the first tofifth embodiments and the eighth embodiment between the collector 450and the suction device 430, and by arranging the flow path covers 152,172, and 182 and the flow path valve 213 on the connecting flow path222, it is possible to regulate the intake air flow amount supplied tothe dust collecting chamber 50.

Hereinafter technical features in which the dust collecting chamber 50according to the tenth embodiment of the disclosure is docked to thedocking station 400 will be described in detail. The dust collectingchamber 50 according to the tenth embodiment may be applied to thecleaning apparatus 1 according to the first embodiment or the cleaningapparatus 1′ according to the eighth embodiment.

FIG. 37 is a view of a part of the dust collecting chamber according tothe tenth embodiment of the disclosure, FIG. 38 is a view illustrating astate before the dust collecting chamber is docked to the dockingstation according to the tenth embodiment of the disclosure, and FIG. 39is a view illustrating a state after the dust collecting chamber isdocked to the docking station according to the tenth embodiment of thedisclosure.

Referring to FIGS. 37 and 38, the dust collecting chamber 50 may includea dust collecting chamber body 53 and the dust collecting chamber door51 configured to open and close the dust collecting chamber body 53 uponthe docking to the docking station 400.

The dust collecting chamber body 53 may be provided in a cylindricalshape. However, the shape of the dust collecting chamber body 53 is notlimited thereto, and thus the dust collecting chamber body 53 may beprovided in a polygonal tubular shape.

The dust collecting chamber door 51 may be arranged at a lower end ofthe dust collecting chamber body 53 and open and close the lower end ofthe dust collecting chamber body 53.

As illustrated above, the dust collecting chamber 50 may include thefirst dust collector 50 a configured to collect foreign substances whichare primarily collected and have a relatively large size, and the seconddust collector 50 b configured to collect foreign substance, which arecollected by the multi-cyclone 52 and have a relatively small size.

Both the first dust collector 50 a and the second dust collector 50 bmay be configured to be opened to the outside upon opening of the dustcollecting chamber door 51. At this time, upon opening of the dustcollecting chamber door 51, both the first dust collector 50 a and thesecond dust collector 50 b may be opened to the outside.

The dust collecting chamber door 51 may include an engaging protrusion51 a engaged with the dust collecting chamber body 53 to maintain thedust collecting chamber 50 at a closed state, and a cap portion 51 bconfigured to prevent foreign substances, which are collected in thesecond dust collector 50 b, from being scattered to the outside upon theclosing of the dust collecting chamber 50.

The dust collecting chamber door 51 may open and close the lower end ofthe dust collecting chamber body 53 while being rotated about a rotaryshaft 51 c arranged at one side of the lower end of the dust collectingchamber body 53.

The dust collecting chamber 50 may include a fixing member 56 arrangedat the other side of the lower end of the dust collecting chamber body53 and configured to prevent the dust collecting chamber door 51 frombeing separated from the lower end of the dust collecting chamber body53 by supporting the engaging protrusion 51 a.

The fixing member 56 may be hooked to the engaging protrusion 51 a toprevent the engaging protrusion 51 a from being separated from the dustcollecting chamber body 53.

The fixing member 56 may include a pusher 56 a configured to release ahooked engagement with the engaging protrusion 51 a by being rotatedupon the application of an external force, and a hook 56 b interlockedwith the pusher 56 a and hook-engaged with the engaging protrusion 51 a.

The fixing member 56 may include an elastic member 56 c configured tomaintain the hook 56 b and the engaging protrusion 51 a in a hookedstate in response to a state of the fixing member 56 not being pressedby the pusher 56 a.

The elastic member 56 c is biased to allow the hook 56 b to be pressedin the direction of the engaging protrusion 51 a so as to maintain thehooked engagement of the hook 56 b and the engaging protrusion 51 a inthe closed state of the dust collecting chamber door 51.

That is, the elastic member 56 c may press the hook 56 b toward theengaging protrusion 51 a side by pressing the hook 56 b toward theopposite direction of the radial direction of the dust collectingchamber body 53.

Upon pressing the pusher 56 a with a force greater than the elasticforce of the elastic member 56 c, the hook 56 b may be rotated inconjunction with the pusher 56 a, and the hooked engagement of the hook56 b and the engaging protrusion 51 a may be released.

The pusher 56 a and the hook 56 b may be arranged in opposite directionsabout the rotation axis of the fixing member 56. Accordingly, inresponse to the pressing of the pusher 56 a, the hook 56 b may be movedin an opposite direction of the pressing direction of the pusher 56 a.

Therefore, upon pressing of the pusher 56 a with the external force inan opposite direction of the radial direction of the dust collectingchamber body 53, the pusher 56 a may be rotated in the oppositedirection of the radial direction of the dust collecting chamber body53, and thus the hook 56 b may be rotated in the opposite direction ofthe radial direction of the dust collecting chamber body 53 and thenmoved in a direction away from the engaging protrusion 51 a.

At this time, the dust collecting chamber door 51 may be separated fromthe dust collecting chamber body 53 by gravity and rotated downward withrespect to the rotary shaft 51 c, and thus the lower end of the dustcollecting chamber body 53 may be opened.

The pusher 56 a may protrude outward of an outer circumferential surfaceof the dust collecting chamber body 53 in the radial direction of thecentral axis of the dust collecting chamber body 53. A user can easilypress the pusher 56 a of the fixing member 56 protruding outward of theouter circumferential surface of the dust collecting chamber body 53,thereby opening the dust collecting chamber 50.

As for the docking station 400, the dust collecting chamber door 51 maybe configured to be opened in response to docking of the dust collectingchamber 50 to the seating portion 442 of the docking station 400.

The docking station 400 may include an opening guide 443 configured topress the pusher 56 a to open the dust collecting chamber door 51 uponseating the dust collecting chamber 50 on the seating portion 442.

The opening guide 443 may be arranged on the inner circumferentialsurface 442 a of the seating portion 442 forming the seating portion442.

The opening guide 443 may be formed as a partial region of the innercircumferential surface 442 a of the seating portion 442 in the samemanner as an embodiment of the disclosure. However, the disclosure isnot limited thereto, and the opening guide 443 may be provided in theshape of a region or a protruding surface that protrudes toward thecenter from the inner circumferential surface 442 a of the seatingportion 442, and a shape such as a protrusion or rib that protrudestoward the center from the inner circumferential surface 442 a.

The inner circumferential surface 442 a of the seating portion 442 maybe provided to have a size substantially corresponding to the outercircumferential surface of the dust collecting chamber body 53.Particularly, a circumference of the inner circumferential surface 442 aof the seating portion 442 and a circumference of the dust collectingchamber body 53 may substantially correspond to each other.

That is, upon docking the dust collecting chamber 50 to the dockingstation 400, the inner circumferential surface 442 a of the seatingportion 442 and the outer circumferential surface of the dust collectingchamber body 53 may face at a predetermined distance.

Accordingly, upon seating the dust collecting chamber 50 on the seatingportion 442, referring to FIG. 39, the outer circumferential surface ofthe dust collecting chamber body 53 may move downward along the innercircumferential surface 442 a of the seating portion 442.

At this time, the pusher 56 a protruding outward than the outercircumferential surface of the dust collecting chamber body 53 may bepressed downward and at the same time, pressed by the opening guide 443that is formed as a part of the inner circumferential surface 442 a ofthe seating portion 442.

Particularly, while the dust collecting chamber 50 is pressed downward,the pusher 56 a arranged on the outside of the outer circumferentialsurface of the dust collecting chamber body 53 may be pressed in thevertical direction by the opening guide 443, and thus the pusher 56 amay be rotated in the opposite direction of the radial direction of theouter circumferential surface of the dust collecting chamber body 53.Therefore, the hooked engagement of the hook 56 b and the engagingprotrusion 51 a may be released and thus the dust collecting chamberdoor 51 may be opened.

Therefore, upon docking the dust collecting chamber 50 to the seatingportion 442, the pusher 56 a may be automatically pressed by the openingguide 443 and thus the dust collecting chamber door 51 may be openedupon the docking of the dust collecting chamber 50 to the dockingstation 400.

Hereinafter a dust collecting chamber 50′ of a cleaning apparatusaccording to an eleventh embodiment of the disclosure will be described.A configuration other than the dust collecting chamber 50′ describedbelow is the same as that of the cleaning apparatus 1″ and the dustcollecting chamber 50 according to the tenth embodiment of thedisclosure and thus a description thereof will be omitted. In addition,the dust collecting chamber of the cleaning apparatus according to theeleventh embodiment may be applied to the cleaning apparatus 1 accordingto the first embodiment or the cleaning apparatus 1′ according to theeighth embodiment.

FIG. 40 is a view of a part of a dust collecting chamber according to aneleventh embodiment of the disclosure.

Referring to FIG. 40, the dust collecting chamber 50′ according to theeleventh embodiment of the disclosure may include a first fixing member57 and a second fixing member 58.

The first fixing member 57 and the second fixing member 58 may berespectively hooked to a first engaging protrusion 51 d and a secondengaging protrusion 51 e arranged on the dust collecting chamber door51.

The first fixing member 57 and the second fixing member 58 each has thesame configuration as that of the fixing member 56 according to thetenth embodiment of the disclosure, and thus a description thereof willbe omitted.

Upon operating the cleaner 10 by a user, the dust collecting chamber 50may be opened because the user accidentally presses the fixing member 26during the operation. That is, the fixing member 26 may open the dustcollecting chamber door 51 using a pressure, and the fixing member 26may be pressed to open the dust collecting chamber 50 regardless of auser intention.

In order to ease this difficulty, the dust collecting chamber 50′according to the eleventh embodiment of the disclosure may be providedwith two fixing members 57 and 58 for fixing the dust collecting chamberdoor 51.

Accordingly, it is possible to ease the difficulty that the dustcollecting chamber 50′ is opened regardless of a user intention whiledriving the cleaner 10. Particularly, two fixing members 57 and 58 inwhich an engagement with the dust collecting chamber door 51 is releasedby the external force may be provided and thus even when a useraccidentally presses one fixing member 57, the other fixing member 58may fix the dust collecting chamber door 51, thereby maintaining theclosed state of the dust collecting chamber door 51.

In order to open the dust collecting chamber door 51, a user must pressboth fixing members 57 and 58. That is, only when the first and secondfixing members 57 and 58 are pressed at the same time, the restrictionon the first engaging protrusion 51 d and the second engaging protrusion51 e may be released so as to open the dust collecting chamber door 51.

The first fixing member 57 and the second fixing member 58 may be spacedapart from each other. A separation distance between the first fixingmember 57 and the second fixing member 58 may vary.

In the same manner as the fixing member 56 of the tenth embodiment ofthe disclosure, upon docking to the docking station 400, the firstfixing member 57 and the second fixing member 58 may be pressed by theopening guide 443 and the hooked engagement with the first engagingprotrusion 51 d and the second engaging protrusion 51 e may be releasedand thus the dust collecting chamber door 51 may be opened.

The opening guide 443 may maintain a pressed state of the first fixingmember 57 and the second fixing member 58 at the same time, and thus thedust collecting chamber door 51 may be opened.

That is, although a plurality of fixing members 57 and 58 is provided,the plurality of fixing members 57 and 58 may be pressed by the openingguide 443 upon docking to the docking station 400, and thus the dustcollecting chamber door 51 may be automatically opened.

At this time, the opening guide 443 may be formed on the entire innercircumferential surface 442 a of the seating portion 442. That is, theopening guide 443 may be formed along the circumferential direction ofthe inner circumferential surface 442 a of the seating portion 442although not shown in the drawing.

Therefore, the first and second fixing members 57 and 58 may be alwayspressed by the opening guide 443 even when the dust collecting chamber50′ is docked to the docking station 400 in any direction in thecircumferential direction of the outer circumferential surface of thedust collecting chamber body 53.

Alternatively, the docking station 400 may include a guide (not shown)configured to allow the dust collecting chamber 50′ to be seated in aspecific direction in the circumferential direction of the outercircumferential surface of the dust collecting chamber body 53 uponseating the dust collecting chamber 50′ on the seating portion 442.

The guide (not shown) may guide the dust collecting chamber 50′ to allowthe dust collecting chamber 50′ to be docked in a direction in which thefirst and second fixing members 57 and 58 substantially overlap with theopening guide 443 in the vertical direction.

As mentioned above, only when the first and second fixing members 57 and58 are pressed, the dust collecting chamber door 51 may be opened.Therefore, upon docking the dust collecting chamber 50′ to the dockingstation 400, the first and second fixing members 57 and 58 may beconsequentially pressed by the opening guide 443 and thus the dustcollecting chamber door 51 may be opened upon the docking of the dustcollecting chamber 50′.

Hereinafter a dust collecting chamber 50″ of a cleaning apparatusaccording to a twelfth embodiment of the disclosure will be described. Aconfiguration other than the dust collecting chamber 50″ described belowis the same as that of the cleaning apparatus 1″ and the dust collectingchamber 50 according to the tenth embodiment of the disclosure and thusa description thereof will be omitted. In addition, the dust collectingchamber of the cleaning apparatus according to the twelfth embodimentmay be applied to the cleaning apparatus 1 according to the firstembodiment or the cleaning apparatus 1′ according to the eighthembodiment.

FIG. 41 is a view illustrating a state before the dust collectingchamber is docked to a docking station according to a twelfth embodimentof the disclosure, FIG. 42 is a view illustrating a state in which anexternal force is applied to a fixing member of the dust collectingchamber according to the twelfth embodiment of the disclosure, and FIG.43 is a view illustrating a state after the dust collecting chamber isdocked to the docking station according to the twelfth embodiment of thedisclosure.

Referring to FIG. 41, the dust collecting chamber 50″ may include afixing member 26 and an auxiliary fixing member 29 configured to fix adust collecting chamber door 51 together with the fixing member 26. Aconfiguration of the dust collecting chamber 50″ according to thetwelfth embodiment other than the auxiliary fixing member 29 is the sameas that of the dust collecting chamber 50 according to the tenthembodiment, and thus a description thereof will be omitted.

The dust collecting chamber door 51 may open and close the lower end ofthe dust collecting chamber body 53 while being rotated about a rotaryshaft 51 c arranged at one side of the lower end of the dust collectingchamber body 53.

The fixing member 56 may be arranged on the other side of the lower endof the dust collecting chamber body 53 and configured to support theengaging protrusion 51 a so as to prevent the dust collecting chamberdoor 51 from being separated from the lower end of the dust collectingchamber body 53.

The fixing member 56 may be hooked to the engaging protrusion 51 a toprevent the engaging protrusion 51 a from being separated from the dustcollecting chamber body 53.

The auxiliary fixing member 29 may prevent a case in which the dustcollecting chamber door 51 is opened regardless of the use intention.That is, it is possible to prevent a case in which the dust collectingchamber door 51 is opened and foreign substances are scattered becausethe user accidentally presses the fixing member 56.

The auxiliary fixing member 29 may be arranged on the rotary shaft 51 cof the dust collecting chamber door 51 so as to limit a rotation of arotary portion 51 f of the dust collecting chamber door 51, therebyfixing the dust collecting chamber door 51 to the dust collectingchamber body 53.

The auxiliary fixing member 59 may include a pusher 59 a configured torelease the limitation of the rotation of the rotary portion 51 f bybeing rotated upon being pressed by an external force, and a limiter 59b interlocked with the pusher 59 a and configured to limit the rotationof the rotary portion 51 f by pressing the rotary portion 51 f to anopposite direction of the rotation direction of the rotary portion 51 f.

The pusher 59 a may be provided to protrude outward of an outercircumferential surface of the dust collecting chamber body 53 in theradial direction of the central axis of the dust collecting chamber body53. A user can easily press the pusher 59 a of the auxiliary fixingmember 59 protruding outward of the outer circumferential surface of thedust collecting chamber body 53, thereby easily opening the dustcollecting chamber 50″.

The auxiliary fixing member 59 may include an elastic member 56 cconfigured to maintain a pressed state of the rotary portion 51 f byallowing the limiter 59 b to press the rotary portion 51 f when theauxiliary fixing member 59 is not pressed by the pusher 59 a.

The elastic member 59 c is biased to allow the limiter 59 b to press therotary portion 51 f toward an opposite direction of the rotationdirection of the rotary portion 51 f in the closed state of the dustcollecting chamber door 51. Therefore, a state in which the limiter 59 blimits the rotation of the rotary portion 51 f may be maintained.

That is, the elastic member 59 c may press the limiter 59 b toward anopposite direction of the radial direction of the dust collectingchamber body 53 to allow the limiter 59 b to be maintained at a positionin which the limiter 59 b limits the rotation of the rotary portion 51f.

The pusher 59 a and the limiter 59 b may be arranged in oppositedirections about the rotation axis of the auxiliary fixing member 59.Accordingly, upon pressing of the pusher 59 a, the limiter 59 b may bemoved in an opposite direction of the pressing direction of the pusher59 a.

Therefore, upon pressing the pusher 59 a with the external force in anopposite direction of the radial direction of the dust collectingchamber body 53, the pusher 59 a may be rotated in the oppositedirection of the radial direction of the dust collecting chamber body53, and thus the limiter 59 b may be rotated in the opposite directionof the radial direction of the dust collecting chamber body 53 and thenmoved in a direction away from the rotary portion 51 f.

As the limiter 59 b is moved in a direction away from the rotary portion51 f, the limiter 59 b may be separated from the position pressed in anopposite direction of the rotational direction of the rotary portion 51f.

In a state in which the hooked engagement of the engaging protrusion 51a and the hook 56 b is released because the fixing member 56 is pressed,when the limiter 59 b is separated from the position pressed in theopposite direction of the rotation direction of the rotary portion 51 f,the dust collecting chamber door 51 may be separated from the dustcollecting chamber body 53 by gravity, and the dust collecting chamberdoor 51 may be rotated downward about the rotary shaft 51 c, and thusthe lower end of the dust collecting chamber body 53 may be opened.

Accordingly, when the user presses only the fixing member 26 withoutpressing the auxiliary fixing member 29 as shown in FIG. 42, the limiter59 b of the dust collecting chamber door 51 may limit the rotation ofthe rotary portion 51 f and thus the dust collecting chamber door 51 maybe fixed to the dust collecting chamber body 53 without rotating andmoving downward.

In order to open the dust collecting chamber door 51, the user mustpress both the fixing member 56 and the auxiliary fixing member 59. Thatis, only when the fixing member 56 and the auxiliary fixing member 59are simultaneously pressed, the fixation of the engaging protrusion 51 amay be released, and the restriction of the rotation of the rotaryportion 51 f may be released, and thus the dust collecting chamber door51 may be opened.

The fixing member 56 and the auxiliary fixing member 59 may be spacedapart from each other. A separation distance between the fixing member56 and the auxiliary fixing member 59 may vary. However, the auxiliaryfixing member 59 may be arranged to substantially correspond to therotary shaft 51 c of the dust collecting chamber door 51, in which therotary portion 51 f is arranged, in the vertical direction.

Referring to FIG. 43, in the same manner as the first and second fixingmembers 57 and 58 according to the eleventh embodiment, when the fixingmember 56 and the auxiliary fixing member 59 are docked to the dockingstation 400, the fixing member 56 and the auxiliary fixing member 59 maybe pressed by the opening guide 443 to release the hooked engagementbetween the engaging protrusion 51 a and the hook 56 b, and the rotationrestriction of the rotary portion 51 f by the limiter 59 b may bereleased. Accordingly, the dust collecting chamber door 51 may beopened.

The opening guide 443 may maintain the pressed state of the fixingmember 56 and the auxiliary fixing member 59 at the same time and thusthe dust collecting chamber door 51 may be opened.

That is, even when a plurality of configurations configured to fix thedust collecting chamber door 51, such as the fixing member 56 and theauxiliary fixing member 59 is provided, all the plurality ofconfigurations may be pressed by the opening guide 443 upon the dockingto the docking station 400, and thus the dust collecting chamber door 51may be automatically opened.

At this time, the opening guide 443 may be formed on the entire innercircumferential surface 442 a of the seating portion 442. That is, theopening guide 443 may be formed along the circumferential direction ofthe inner circumferential surface 442 a of the seating portion 442although not shown in the drawing.

Therefore, even when the dust collecting chamber 50″ is docked to thedocking station 400 in any one direction in the circumferentialdirection of the outer circumferential surface of the dust collectingchamber body 53, the fixing member 56 and the auxiliary fixing member 59may be pressed by the opening guide 443.

Alternatively, the docking station 400 may include a guide (not shown)configured to allow the dust collecting chamber 50″ to be seated in aspecific direction in the circumferential direction of the outercircumferential surface of the dust collecting chamber body 53 uponseating the dust collecting chamber 50″ on the seating portion 442.

As mentioned above, only when the fixing member 56 and the auxiliaryfixing member 59 are pressed, the dust collecting chamber door 51 may beopened. Therefore, upon docking the dust collecting chamber 50″ to thedocking station 400, the fixing member 56 and the auxiliary fixingmember 59 may be consequentially pressed by the opening guide 443 andthus the dust collecting chamber door 51 may be opened upon the dockingof the dust collecting chamber 50″.

Hereinafter technical features in which, a dust collecting chamber 60according to a thirteenth embodiment of the disclosure is docked to thedocking station 400, will be described in detail. The dust collectingchamber 60 according to the thirteenth embodiment may be applied to thecleaning apparatus 1 according to the first embodiment or the cleaningapparatus 1′ according to the eighth embodiment.

FIG. 44 is a view illustrating a part of a dust collecting chamber in aclosed state according to the thirteenth embodiment of the disclosure,FIG. 45 is a view illustrating a part of the dust collecting chamber inan open state according to the thirteenth embodiment of the disclosure,FIG. 46 is a view illustrating a seating portion according to thethirteenth embodiment of the disclosure, and FIG. 47 is a viewillustrating a state before the dust collecting chamber is docked to adocking station according to the thirteenth embodiment of thedisclosure.

Referring to FIGS. 44 to 47, the dust collecting chamber 60 may includea dust collecting chamber body 63 and a dust collecting chamber door 61configured to open and close the dust collecting chamber body 63 uponthe docking of the dust collecting chamber body 63 to the dockingstation 400.

The dust collecting chamber body 63 may include a cylindrical shapeextending in a long axis X of the dust collecting chamber or in a longaxis X of the dust collecting chamber body 63. However, the shape of thedust collecting chamber body 63 is not limited thereto, and thus thedust collecting chamber body 63 may be provided in a polygonal tubularshape.

The dust collecting chamber door 61 may be arranged at a lower end ofthe dust collecting chamber body 63 and configured to open and close thelower end of the dust collecting chamber body 63.

As illustrated above, the dust collecting chamber 60 may include a firstdust collector 60 a configured to collect foreign substances which areprimarily collected and have a relatively large size, and a second dustcollector 60 b configured to collect foreign substance, which arecollected by a multi-cyclone 62 and have a relatively small size.

Both the first dust collector 60 a and the second dust collector 60 bmay be opened to the outside upon opening of the dust collecting chamberdoor 61. At this time, upon opening of the dust collecting chamber door61, both the first dust collector 60 a and the second dust collector 60b may be opened to the outside.

The dust collecting chamber door 61 may include an engaging protrusion61 a engaged with the dust collecting chamber body 63 to maintain thedust collecting chamber 60 at a closed state, and a cap portion 61 bconfigured to prevent foreign substances, which are collected in thesecond dust collector 60 b, from being scattered to the outside upon theclosing of the dust collecting chamber 60.

The dust collecting chamber door 61 may open and close the lower end ofthe dust collecting chamber body 63 while being rotated about a rotaryshaft 61 c arranged at one side of the lower end of the dust collectingchamber body 63.

The dust collecting chamber 60 may include a fixing device 66 arrangedat the other side of the lower end of the dust collecting chamber body63 and configured to support the engaging protrusion 61 a so as toprevent the dust collecting chamber door 61 from being separated fromthe lower end of the dust collecting chamber body 63.

The fixing device 66 may include a hook 66 a configured to be hooked tothe engaging protrusion 61 a to prevent the engaging protrusion 61 afrom being separated from the dust collecting chamber body 63.

The fixing device 66 may include a pusher 66 b configured to release thehook engagement between the hook 66 a and the engaging protrusion 61 aby being moved upon the application of an external force.

The pusher 66 b may be configured to be pressed by a user so as to movethe hook 66 a, thereby releasing the engagement between the hook 66 aand the engaging protrusion 61 a.

The dust collecting chamber 50, 50′, and 50″ disclosed in the tenth totwelfth embodiments described above are provided to allow a user topress the pusher toward an opposite direction of a radial direction r ofthe dust collecting chamber body with respect to the long axis X of thedust collecting chamber body 63 so as to move the fixing member toward aradial direction r of the dust collecting chamber body, therebyseparating the fixing member from the engaging protrusion.

However, the dust collecting chamber 60 according to the thirteenthembodiment of the disclosure may be provided to allow a user to pressthe pusher 66 b toward a circumferential direction c of the dustcollecting chamber body 63 with respect to the long axis X of the dustcollecting chamber body 63, thereby opening the dust collecting chamberdoor 61.

As the pusher 66 b moves in the circumferential direction c of the dustcollecting chamber body 63, the pusher 66 b may press the hook 66 atoward the radial direction r of the dust collecting chamber body 63,and accordingly, the hook engagement between the hook 66 a and theengaging protrusion 61 a may be released.

The fixing device 66 may include an elastic member 66 c configured tomaintain the hook state between the hook 66 a and the engagingprotrusion 61 a in response to a state of the hook 66 a not beingpressed by the pusher 66 b.

The elastic member 66 c may be configured to allow the hook 66 a to bebiased in the direction of the engaging protrusion 61 a so as tomaintain the hook engagement between the hook 66 a and the engagingprotrusion 61 a in the closed state of the dust collecting chamber door61.

While moving in the circumferential direction c of the dust collectingchamber body 63, the pusher 66 b may press the hook 66 a toward theradial direction r of the dust collecting chamber body 63 that is anopposite direction of a direction in which the hook 66 a is biased.

That is, although not shown in the drawing, the pusher 66 b may includean inclined surface provided in a part in contact with the hook 66 acaused by the movement thereof, and thus the hook 66 a may be pressed inthe radial direction r of the dust collecting chamber body 63 along theinclined surface.

Upon operating a cleaner 10 by a user, the dust collecting chamber 60may be opened because the user accidentally presses the pusher 66 b ofthe fixing device 66 during the manipulation. That is, the fixing device66 may open the dust collecting chamber door 61 by a pressure of thepusher 66 b, and the fixing device 66 may be pressed regardless of auser intention, thereby opening the dust collecting chamber 60.

In order to ease this difficulty, the fixing device 66 of the dustcollecting chamber 60 according to the thirteenth embodiment of thedisclosure may include two pushers 66 b-1 and 66 b-2.

The two pushers 66 b-1 and 66 b-2 may be configured to be pressed in adirection and an opposite direction, respectively, with respect to thecircumferential direction c of the dust collecting chamber body 63.

Only in response to a pressure in a direction and an opposite direction,respectively, with respect to the circumferential direction c of thedust collecting chamber body 63, the two pushers 66 b-1 and 66 b-2 maypress the hook 66 a so as to allow the dust collecting chamber door 61to be opened.

For example, upon pressing the pusher 66 b with a force greater than theelastic force of the elastic member 66 c, the hook 66 a may be moved inconnection with the pusher 66 b and thus the hook engagement between thehook 66 a and the engaging protrusion 61 a may be released.

At this time, the elastic force of the elastic member 66 c may have aforce greater than a force that is applied to the hook 66 a by any onepusher 66 b-1 or 66 b-2 upon pressing the hook 66 a by any one pusher 66b-1 or 66 b-2. Therefore, it is possible to prevent a case in which thehook 66 a is separated from the engaging protrusion 61 a upon pressingonly one pusher 66 b-1 or 66 b-2.

That is, in response to the hook 66 a being pressed by the two pushers66 b-1 and 66 b-2 because the two pushers 66 b-1 and 66 b-2 are pushed,a force greater than the elastic force of the elastic member 66 c may betransferred to the hook 66 a.

Accordingly, even when a user accidentally presses any one of the twopushers 66 b-1 and 66 b-2 during cleaning, the dust collecting chamberdoor 61 may be fixed to the fixing device 66 without being separatedfrom the dust collecting chamber body 63.

The docking station 400 may be configured to allow the dust collectingchamber door 61 to be opened in response to docking of the dustcollecting chamber 60 to the seating portion 442 of the docking station400.

The docking station 400 may include an opening guide 444 configured topress the pusher 66 b to open the dust collecting chamber door 61 inresponse to seating the dust collecting chamber 60 on the seatingportion 442.

The opening guide 444 may be arranged on an inner circumferentialsurface 442 a of the seating portion 442 forming the seating portion442.

The opening guide 444 may be provided in a shape protruding toward thecenter of the seating portion 442 from the inner circumferential surface442 a of the seating portion 442 in the same manner as an embodiment ofthe disclosure. However, the disclosure is not limited thereto, and thusthe opening guide 444 may be formed as a partial region of the innercircumferential surface 442 a. Alternatively, the opening guide 444 maybe formed as shapes such as a protruding surface, a protrusion or a ribthat protrude toward the center from the inner circumferential surface442 a of the seating portion 442.

The inner circumferential surface 442 a of the seating portion 442 mayhave a diameter substantially greater than a diameter of an outercircumferential surface of the dust collecting chamber body 63. This isbecause the opening guide 444 is formed to protrude toward the center ofthe seating portion 442.

However, the disclosure is not limited thereto, and the innercircumferential surface 442 a of the seating portion 442 may have a sizesubstantially corresponding to a diameter of the outer circumferentialsurface of the dust collecting chamber body 63 in response to the shapeof the opening guide 444 formed in a partial region of the innercircumferential surface 442 a.

In response to docking of the dust collecting chamber 60 to the dockingstation 400, the inner circumferential surface 442 a of the seatingportion 442 and the outer circumferential surface of the dust collectingchamber body 63 may face to each other at a predetermined distance.

Accordingly, as illustrated in FIGS. 46 and 47, in response to seatingof the dust collecting chamber 60 on the seating portion 442, the outercircumferential surface of the dust collecting chamber body 63 may movedownward along the inner circumferential surface 442 a of the seatingportion 442.

The opening guide 444 may be provided in a ring shape extending in thecircumferential direction of the inner circumferential surface 442 a ofthe seating portion 442 and protruding toward the center direction ofthe seating portion 442.

The opening guide 444 may include an open region 444 c provided in theopening guide 444 in the circumferential direction of the innercircumferential surface 442 a of the seating portion 442. That is, theopen region 444 c may be formed in a region where the ring-shapedopening guide 444 is cut.

The open region 444 c is a region in which the fixing device 66 isseated in response to the docking of the dust collecting chamber 60 tothe seating portion 442.

In response to the fixing device 66 and the open region 444 c not beingplaced at a position corresponding to each other with respect to adirection, to which the dust collecting chamber 60 is docked, during thedust collecting chamber 60 is docked to the seating portion 442, thedocking of the dust collecting chamber 60 may be restricted by aprotruding portion 444 d of the opening guide 444.

The protruding portion 444 d of the opening guide 444 may guide the dustcollecting chamber 60 to allow the fixing device 66 and the open region444 c to be placed in a corresponding position with respect to adirection to which the dust collecting chamber 60 is docked.

The opening guide 444 may include an inclined portion 444 a disposed ata portion, in which the opening guide 444 is cut, and provided to beinclined with respect to the direction to which the dust collectingchamber 60 is docked.

The opening guide 444 may include a pressure holding portion 444 bprovided to extend from the inclined portion 444 a and configured topress the pusher 66 b to maintain the pusher 66 b, which is pressed bythe inclined portion 444 a, in a pressed state.

The pressure holding portion 444 b may be provided to extend downwardfrom the lower end of the inclined portion 444 a. The pressure holdingportion 444 b may be provided to extend from the lower end of theinclined portion 444 a toward a direction corresponding to the dockingdirection of the dust collecting chamber 60.

The fixing device 66, which protrudes outward from the outercircumferential surface of the dust collecting chamber body 66, may bedocked to the seating portion 442 together with the dust collectingchamber body 63 and come in contact with the inclined portion 444 a ofthe opening guide 444 and then be pressed toward the circumferentialdirection c of the dust collecting chamber body 63 along the inclinedportion 444 a.

Particularly, as the dust collecting chamber 60 is pressed downward, thefixing device 66 may move downward on the open region 444 c and then thepusher 66 b may come into contact with the inclined portion 444 a.

Due to the continuous pressure of the dust collecting chamber 60, thepusher 66 b may be lowered along the inclined portion 444 a and at thesame time, the pusher 66 b may be pressed by the inclined portion 444 a.

That is, the inclined portion 444 a may press the pusher 66 b toward thecircumferential direction c of the dust collecting chamber body 63, andaccordingly, the hook engagement between the hook 66 a and the engagingprotrusion 61 a may be released. Therefore, the dust collecting chamberdoor 61 may be opened in the seating portion 442.

In response to the docking of the dust collecting chamber 60 to theseating portion 442, the pusher 66 b may be maintained at a state ofbeing pressed by the pressure holding portion 444 b in thecircumferential direction c of the dust collecting chamber body 63.

Accordingly, in response to the docking of the dust collecting chamber60 to the seating portion 442, the dust collecting chamber 60 may beopened as the dust collecting chamber door 61 is docked to the seatingportion 442 by the opening guide 444.

Hereinafter technical features in which a dust collecting chamber 50according to a fourteenth embodiment of the disclosure is docked to thedocking station 400 will be described in detail. A configuration otherthan a lighting device 90 of the docking station 400 according to thefourteenth embodiment described below is the same as that of the dockingstation 400 and the dust collecting chamber 50 according to the tenthembodiment of the disclosure, and thus a description thereof will beomitted.

In addition, the lighting device 90 described below may be easilyapplied to the docking stations 100, 300, and 400 disclosed in thefirst, eighth, and tenth embodiments described above.

FIG. 48 is a view illustrating a state in which a dust collectingchamber is being docked to a docking station according to an embodimentof the disclosure, and FIG. 49 is a side cross-sectional view of thedocking station according to an embodiment of the disclosure.

The lighting device 90 may be configured to emit light toward the dustcollecting chamber 50 to allow a user to recognize a process of removingdust from the inside of the dust collecting chamber 50.

That is, the recognition about foreign substances remaining inside thedust collecting chamber 50 may be increased by the lighting device 90.

In some cases, in response to the foreign substances inside the dustcollecting chamber 50 not being completely removed, a user can easilydetermine this state with the naked eye and input a restart signal tothe docking station 400.

The lighting device 90 may be disposed inside the seating portion 442.Particularly, the lighting device 90 may be installed at a lower portionof the seating portion 442 and configured to emit light toward the dustcollecting chamber 50.

The lighting device 90 may include a light emitting device such as alight emitting diode (LED). However, the disclosure is not limitedthereto, and the lighting device 90 may include components configured toemit light toward the dust collecting chamber 50.

The docking station 400 may include a switch unit 460 configured todetect the docking of the dust collecting chamber 50 to the dockinghousing 440 and transmit a signal for driving the suction device 430,the flow rate regulator 220, and the lighting device 90.

In response to the docking of the dustcollecting chamber 50 to the seating portion 442, the switch unit 460may be pressed against the outer circumferential surface of the dustcollecting chamber body 53 and then turned on.

In response to turning on of the switch unit 460, a signal may betransmitted to the controller (not shown), and the controller (notshown) may control each configuration to allow the suction device 430,the flow rate regulator 220, and the lighting device 90 to be driven.

The suction device 430, the flow rate regulator 220, and the lightingdevice 90 may be driven for a predetermined period of time after theswitch unit 460 is turned on, and then the driving of the suction device430, the flow rate regulator 220, and the lighting device 90 may beterminated.

The docking station 400 may include an inputter 401 configured totransmit a signal to the controller (not shown) so as to re-drive thesuction device 430 and the flow rate regulator 220 in which drivingthereof is terminated.

Upon pressing the inputter 401 by a user, a signal may be transmitted tothe controller (not shown) so as to allow the suction device 430 and theflow rate regulator 220, in which driving thereof is terminated, to bedriven again. In addition, the lighting device 90 may be configured tobe driven again by the inputter 401.

As mentioned above, the suction device 430, the flow rate regulator 220,and the lighting device 90 may be driven for a predetermined period oftime after the switch unit 460 is turned on, and then the drivingthereof may be terminated. However, the foreign substances in the dustcollecting chamber 50 may not be completely removed during a drivingtime.

A user can drive the suction device 430 and the flow rate regulator 220by pressing the inputter 401 as needed because the user can easilyobserve the inside of the dust collecting chamber 50 by the lightingdevice 90.

The inputter 401 may be provided in a configuration such as a button ora switch, but is not limited thereto. Therefore, the inputter 401 may beformed as a touch display configured to recognize a user's touch.

Hereinafter a flow rate regulator 220 according to a fifteenthembodiment of the disclosure will be described. A configuration otherthan a return switch 227 of the flow rate regulator 220 according to thefifteenth embodiment described below is the same as that of the flowrate regulator 220 according to the tenth embodiment of the disclosure,and thus a description thereof will be omitted.

In addition, the return switch 227 described below may be included innot only the flow rate regulator 220 according to the above-describedtenth embodiment, but also the return switch 227 may be included in theflow rate regulator 150, 170, 180, and 210 disclosed in each of theabove-described embodiments.

As described in the tenth embodiment, the flow rate regulator 220 mayinclude the plate 228 configured to selectively open and close theconnecting flow path 222. The plate 228 may be configured to open orclose the connecting flow path 222 by being translated in one direction.

In addition, as described above, the flow rate regulator 220 may bedriven for a predetermined time after the dust collecting chamber 50 isdocked to the docking station 400, and then the driving thereof may beterminated.

In this case, the rotation of the drive motor 224 may be terminated inresponse to the termination of the driving, and the plate 228 may bedisposed according to a position at which a shaft 226, which isinterlocked with the drive motor 224, is disposed.

That is, in response to the termination of the driving of the flow rateregulator 220, the plate 280 may be arranged at a position of fullyopening the connecting flow path 222, at a position of fully closing theconnecting flow path 222 or at a position of closing at least oneportion of the connecting flow path 222.

The connecting flow path 222 may allow the suction device 430 tocommunicate with the collector 450, and in response to the terminationof the driving of the flow rate regulator 220 in a state in which atleast one portion of the connecting flow path 222 is open, foreignsubstances scattered in the collector 450 may flow into the suctiondevice 430 through the connecting flow path 222.

The suction device 430 may include electrical components such as asuction fan 431 configured to suction air, and the suction device 430may be damaged by foreign substances continuously flowing into theconnecting flow path 222 or contaminated intake airflow may be formed bythe introduced foreign substances introduced through the suction fan431.

FIG. 50 is a view illustrating a state in which a flow rate regulatoropens a connecting flow path according to an embodiment of thedisclosure, and FIG. 51 is a view illustrating a state in which the flowrate regulator closes the connecting flow path according to anembodiment of the disclosure.

In order to prevent this, referring to FIGS. 50 and 51, the flow rateregulator 220 may detect a position of the plate 228 after the drivingof the flow rate regulator 220 is terminated according to a driving endsignal transmitted from the controller (not shown). Accordingly, theflow rate regulator 220 may perform the additional driving so that thedriving of the flow rate regulator 220 is terminated after the plate 228is moved to the position of fully closing the connecting flow path 222.

That is, although the driving end signal is transmitted to the flow rateregulator 220 from the controller (not shown), the plate 228 may not beplaced in the position of closing the connecting flow path 222 at thetime of the termination of the driving of the flow rate regulator 220.

At this time, the flow rate regulator 220 may detect the position of theplate 228, and additionally drive the drive motor 224 to move the plate228 to the position of closing the connecting flow path 222, therebyarranging the plate 228 to the position of closing the connecting flowpath 222.

The flow rate regulator 220 may be configured to terminate the entiredriving thereof in response to detecting the position of the plate 228corresponding to the position of closing the connecting flow path 222.

The flow rate regulator 220 may include the return switch 227 configuredto detect a position of the plate 228.

The return switch 227 may include a detector 227 a provided in contactwith a side surface 228 a of the plate 228 and configured to detect aposition of the plate 228 based on whether to be in contact with theside surface 228 a of the plate 228.

The return switch 227 may be disposed adjacent to the connecting flowpath 222. Particularly, the return switch 227 may be disposed parallelto the connecting flow path 222 in a direction perpendicular to thedirection in which the plate 228 is translated.

Accordingly, the position of the plate 228, in a state in which the sidesurface 228 a of the plate 228 presses the detector 227 a, may be aposition where the plate 228 closes the connecting flow path 222.

In contrast, the position of the plate 228, in a state in which the sidesurface 228 a of the plate 228 is moved and does not press the detector227 a, may be a position where the plate 228 is away from the connectingflow path 222 and the plate 228 opens the connecting flow path 222.

In response to the detector 227 a being pressed against the side surface228 a of the plate 228, the return switch 227 may be turned off, and inresponse to the detector 227 a not being pressed against the sidesurface 228 a of the plate 228, the return switch 227 may be turned on.

The position of the plate 228 may be detected depending on whether thedetector 227 a is pressed. That is, in response to the turn-on of thereturn switch 227, the controller (not shown) may detect a position ofthe plate 228 as the position in which the plate 228 opens theconnecting flow path 222, and in response to the turn-off of the returnswitch 227, the controller (not shown) may detect a position of theplate 228 as the position in which the plate 228 closes the connectingflow path 222.

Accordingly, the controller (not shown) may terminate the entire drivingof the flow rate regulator 220 in response to the turn-off of the returnswitch 227 at the point of time in which the driving of the flow rateregulator 220 and the suction device 430 is terminated after apredetermined time elapses from when the dust collecting chamber 50 isdocked to the docking station 400.

In contrast, in response to the turn-on of the return switch 227 at thepoint of time in which the driving of the flow rate regulator 220 andthe suction device 430 is terminated after the predetermined timeelapses from when the dust collecting chamber 50 is docked to thedocking station 400, the controller (not shown) may additionally drivethe drive motor 224 until the return switch 227 of the flow rateregulator 220 is turned off, and accordingly, the controller (not shown)may terminate the entire driving thereof in response to the turn off ofthe return switch 227 by the plate 228 being additionally moved.

Hereinafter a flow rate regulator 230 according to a sixteenthembodiment of the disclosure will be described. A configuration otherthan a bypass 240 of the flow rate regulator 230 according to thesixteenth embodiment described below is the same as that of the flowrate regulator 220 according to the tenth and the fifth embodiment ofthe disclosure, and thus a description thereof will be omitted.

In addition, the bypass 240 described below may be included in not onlythe flow rate regulator 220 according to the above-described tenth andfifth embodiment, but also the bypass 240 may be included in the flowrate regulator 150, 170, 180, and 210 disclosed in each of theabove-described embodiments.

FIG. 52 is an exploded perspective view of a flow rate regulatoraccording to a sixteenth embodiment of the disclosure, FIG. 53 is a sidecross-sectional view illustrating a state in which a damper is closed inthe flow rate regulator according to the sixteenth embodiment of thedisclosure, and FIG. 54 is a side cross-sectional view illustrating astate in which the damper is closed in the flow rate regulator accordingto the sixteenth embodiment of the disclosure.

Referring to FIGS. 52 to 54, the flow rate regulator 230 may include aflow path housing 231 forming a connecting flow path 232 configured toconnect a collector 450 to a suction device 430.

Particularly, the connecting flow path 232 may be configured to connectthe collector 450 to the suction device 430 and to allow air to flow.Accordingly, the collector 450 and the suction device 430 maycommunicate with each other through the connecting flow path 232, andthe intake air flow generated by the suction device 430 may move to thecollector 450 through the connecting flow path 232.

The connecting flow path 151 disclosed in the first to sixth embodimentsmay be connected to the dust collecting guide 30 and configured to allowthe outside air to flow to the dust collecting guide 30, but theconnecting flow path 212 according to the eighth embodiment, theconnecting flow path 222 according to the tenth embodiment, and theconnecting flow path 232 according to the sixteenth embodiment may beconfigured to connect the suction device 430 to the collector 450.

The flow rate regulator 230 may include a flow path valve 233 arrangedon the connecting flow path 232 and configured to open and close theconnecting flow path 232 to regulate the intake air flow in theconnecting flow path 232.

The flow rate regulator 230 may include a drive motor 234 configured toallow the flow path valve 233 to open and close the connecting flow path232 by using the rotation thereof.

A rotating member 235 may be arranged on a rotation axis of the drivemotor 234. The rotating member 235 may be provided in a disk shape andmay be rotated about the rotation axis of the drive motor 234.

A shaft 236 may be arranged on one side of the rotating member 235. Theshaft 236 may be arranged on the outside of the rotation axis of therotating member 235. Accordingly, the shaft 236 may revolve around therotation axis of the drive motor 234 upon driving of the drive motor234.

The flow path valve 233 may include a slit 239 into which the shaft 236is inserted. The slit 229 may allow the flow path valve 233 toreciprocate in conjunction with the revolution of the shaft 236 insertedinto the slit 239.

The flow path valve 233 may include a plate 228 configured to performtranslational motion in conjunction with the slit 239, and configured toselectively open and close the connecting flow path 232 throughtranslational motion.

An operation, in which the flow path valve 233 selectively opens andcloses the connecting flow path 232 while moving, is the same as theoperation of the flow rate regulator 220 according to the tenthembodiment, and a description thereof will be omitted.

In response to closing of the connecting flow path 232 by the plate 238of the flow path valve 233, a vacuum pressure on the suction device 430and the connecting flow path 232 may increase. Accordingly, because thesuction device 430, in particular, the suction fan 431 is overloaded,the reliability of the docking station 400 may be deteriorated.

In addition, as the vacuum pressure between the suction device 430 andthe connecting flow path 232 increases, noise may be generated more thannecessary.

Accordingly, the flow rate regulator 230 according to the sixteenthembodiment may maintain a smooth flow of the intake air flow even whenthe plate 238 closes the connecting flow path 232, thereby preventingnoise and overload on the suction fan 431.

Particularly, the flow rate regulator 230 may include the bypass 240configured to allow intake air flow to be smoothly formed even in aclosed state of the connecting flow path 232 by the plate 238.

The bypass 240 may include a bypass flow path 241 in communication withone side of the connecting flow path 232 and a damper 242 connected tothe other end of the bypass flow path 241 and configured to be opened tothe outside in response to the vacuum pressure equal to or higher than acertain value in the bypass flow path 241.

The bypass 240 may include a bypass pipe 243 forming the bypass flowpath 241.

One end of the bypass pipe 243 may be connected to the connecting flowpath 232 and the other end of the bypass pipe 243 may include acommunication hole 244 communicating with the outside of the bypass pipe243.

The bypass pipe 243 may have a hollow shape, and the bypass flow path241 may be formed inside the bypass pipe 243.

The bypass pipe 243 may be provided to extend from one side of the flowpath housing 231 to the outside of the flow path housing 231.

The damper 242 may include a mass body 242 a disposed inside the bypasspipe 243 and movable inside the bypass pipe 243, and an elastic member242 b configured to transmit an elastic force to the mass body 242 a.

The damper 242 may be configured to stably maintain the vacuum pressureinside the connecting flow path 232 while opening and closing thecommunication hole 244. The damper 242 may be configured to lower thevacuum pressure by opening the communication hole 244 in response to theincrease in the vacuum pressure in the connecting flow path 232 and thesuction device 430 connected thereto caused by the closing of theconnecting flow path 232.

That is, the damper 242 may close the communication hole 244 in the openstate of the connecting flow path 232, and the damper 242 may open thecommunication hole 244 in response to the increase in the vacuumpressure in the connecting flow path 232 and the suction device 430 inthe closed state of the connecting flow path 232.

Particularly, the mass body 242 a of the damper 242 may be disposedinside the bypass pipe 243, and the elastic member 242 b configured topress the mass body 242 a may transmit the elastic force to the massbody 242 a to allow the mass body 242 a to be biased toward thecommunication hole 244.

A diameter of the mass body 242 a may greater than a diameter of thecommunication hole 244 and thus even when the mass body 242 a is biasedtoward the communication hole 244, the mass body 242 a may be preventedfrom being separated toward the outside of the flow rate regulator 230through the communication hole 244.

The mass body 242 a may be biased toward the communication hole 244 andthus the communication hole 244 may be maintained in a closed state.That is, in response to the external force that is not transmitted tothe mass body 242 a or in response to a force, which is less than theelastic force transmitted by the elastic member 242 b, being transmittedto the mass body 242 a, the damper 242 may maintain the closed state ofthe communication hole 244.

In response to closing of the connecting flow path 232 by the plate 238,the intake air flow formed toward the collector 450 may be blocked, andaccordingly, the intake air flow may flow in the connecting flow path232 and the suction device 430. Therefore, the vacuum pressure in theconnecting flow path 232 and the suction device 430 may increase.

In this case, the intake air flow may be transmitted to the damper 242through the bypass flow path 341. The intake air flow may transmit thesuction force to the mass body 242 a, and in response to the suctionpower of the intake air flow being greater than the elastic force of theelastic member 242 b, the mass body 242 a may be moved in an oppositedirection of the biased direction by the intake air flow.

As the mass body 242 a is moved by the intake air flow, thecommunication hole 244 may be opened, and the intake air flow may flowfrom the outside of the flow rate regulator 230 through thecommunication hole 244. Therefore, the vacuum pressure in the connectingflow path 232 and the suction device 430 may be maintained at apredetermined level.

That is, in response to the increase in the vacuum pressure in theconnecting flow path 232 and the suction device 430, the mass body 242 amay be moved by the internal vacuum pressure, and accordingly, thecommunication hole 244, which is closed by the mass body 242 a, may beopened.

The connecting flow path 232 may communicate with the outside throughthe bypass flow path 241, and the vacuum pressure in the connecting flowpath 232 and the suction device 430 connected to the connecting flowpath 232 may be lowered, thereby reducing noise and relieving theoverload.

Therefore, even when the connecting flow path 232 is closed by the flowrate regulator 230, the suction device 430 may be driven in the samemanner. However, by using the bypass 240, the vacuum pressure in theconnecting flow path 232 and the suction device 430 may be preventedfrom increasing to a predetermined value regardless of whether theconnecting flow path 232 is closed or not.
